A Guide to Choosing Fiber Optic Spectrometer

Here is a guide to inform you of the factors to consider before purchasing a fiber optic spectrometer.

 

When doing experiments that require configuration of a spectrometer, the steps of choosing a fiber optic is often overlooked. Different factors are there to be considered before choosing a fiber optic spectrometer. Some of the considerations involve different parts of the cable. Considering factors relating to the diameter of the core and absorption are tackled afterward in this article. First of all, let us take a look at the working principle of fiber optic cables and the techniques it uses to transfer data from one point to the other.

 

Fiber Optic – What is it?

 

As others consider it as a ‘light pipe’ a fiber optic cable can be defined as a physical data transmission medium that carries data packages in the form of light signals from one place to the other. The cables guide light through the core in the inner side which is comprised of a spectrum that conducts internal reflection.

 

Factors to Consider

 

What are the factors to consider when selecting a fiber optic cable? Here are some of the considerations that should ring in your mind when you are selecting the best cable to use for transmission.

 

Diameter of the Core

 

In a fiber optic cable, all the light to be transmitted is collected in the core. This means that the diameter of the core determines the number of light signals that can be transmitted through the cable at a time. However, the larger the core the more sensitive is the cable to electromagnetic noise which may lead to distortion of the data under the transmission. The pixel height of the detector should be the first consideration. The lenses are used to focus the image on the array along the axis without distorting its contents. This leads to light being directed to the pixel hence increasing the sensitivity of the setup.

 

Absorption

 

This is also one of the important features you are supposed to consider when choosing a fiber optic cable. In case the fiber absorbs the light, it won’t be detected by the spectrometer. In the manufacturing of the cables, OH ions are doped into the glass using plasma torches which softens the bulbs for easy drawing into fibers. Absorption is created by the presence of these ions which in turn interferes with the measurements of the broadband in the affected region.

 

However, the ultraviolet spectrum also has severe properties of absorption. Solarization, a photochemical effect in the ultraviolet spectrum causes the absorption. The effect worsens over time as the spectrum is exposed to factors below 290nm. Due to such reasons, you are advised to be keen and pay special attention when selecting a fiber optic cable for a special purpose transmission. An extra tip — it is best if you choose the lowest OH when you are operating the NIR spectra. However, if you work in almost UV spectral length, use standard fiber optics which is commonly referred to as UV fiber. When you choose a fiber optic spectrometer put into consideration the factors named above in order to choose the best one for your needs.

Beat The Hassles By Having A Replaceable-Slit Spectrometer

The critical role of the spectrometer slit to the performance of the instrument makes it a factor that must be considered when making a purchase, and now with replaceable-slit models, all needs are catered for easily.

Spectroscopy is a highly demanding field of research, and when looking to purchase instruments for different applications, it is essential to have lots of interests in the details. The spectrometer is the hallmark instrument which is a must-have for all applications in the field and purchasing one should be backed with the guarantee of quality. This often involves taking great interests on the brand or manufacturer that released the model and its specifications which must be able to meet and exceed expectations. A focus on the manufacturer is typically to have the confidence of a product that will be able to perform for longer with no limitations arising from its design.

While considering the spectrometer specifications, the slit is one of the determining factors as to the performance to be expected from the instrument. This is primarily because it determines the amount of light that gets into the spectrometer for processing and optical performance. In general, a wider slit increases the amount of light which reaches the optical bench, but this is always at the expense of the optical resolution. The vice versa is also true as a smaller slit decreases the amount of light that it allows through but will always give higher optical resolutions.
It is, therefore, a tough balance to maintain when considering the slit as every scientist always wants a spectrometer that will enable them to have the best results from every application. The problem is that from time to time different applications often require slits of different sizes and resolutions. This has for long necessitated a lot of professionals and organizations to invest in several spectrometers because of one single aspect which is the slit.

Times have however, and now no one ever needs to incur the costs of purchasing several instruments because of the spectrometer slit when there is an all-in-one solution. Avantes has taken the pains of developing a special model which provides users with the freedom to quickly change the slit depending on the current application. For many scientists, this is a dream come true as they get to have the best of both worlds in a single product. The first advantage is the confidence of using a product from a leading manufacturer that is famous for its top-class solutions. There is an equal gain in having ease in switching from one slit to the other without having to invest in another instrument.

The simplicity of replacing the slits is impressive as all it takes is using a screwdriver to remove the current slit and replacing it with another of choice. A slit set comes complete with all the standard slits of 25, 50, 100 and 200 μm which are used in most applications. No recalibration is required when making the changes as the spectrometers are built with high-precision slit positioning. This makes the slit-replaceable option a perfect solution which can be embraced for all spectroscopy solutions.

What you should know about Raman Spectroscopy

Spectroscopy is the study of interactions between atoms and molecules and an electromagnetic spectrum. It’s applied as a means of identifying and collecting data about various atoms and molecules. If you’re interested in this field, getting more information before opting for the best Raman microscope price in the market can ensure you make a quality purchase.

Microscopy has grown in leaps and bounds since its invention, with a variety of other analytical branches emerging from this field of practice. One of the more popular methods of investigation used in physical and analytical chemistry is spectroscopy. This is the study of the interactivity between matter and an electromagnetic spectrum. Different molecules and atoms emit and absorb light at certain wavelengths. By studying these wavelengths, you can identify the contents of a molecule using an established spectrum.

Raman spectroscopy has emerged as the most common application used in this field. Its non-destructive approach ensures that the molecular structure of the content being studied is not destroyed during the process. These spectroscopy systems can be combined with suitable microscopes to explore a variety of elements. Acquiring more information about these instruments however is crucial if you’re considering its purchase. Getting the best Raman microscope price is only fruitful if the device chosen is suitable for your needs.

How Raman Spectroscopy Works

Raman spectroscopy is used to obtain quality information about an atom or molecule, including its chemical structure, crystallinity, phase, and polymorphy, among other elements. This data is acquired by studying the interactions that take place between light and the chemical bonds found in a substance. The approach is based on a light scattering technique, whereby a molecule is exposed to a high-intensity laser light source from which it scatters incident light.

Most of the light that is scattered during this process is on the same wavelength as the laser light source and is known as Rayleigh scatter. A minimal amount, however, is also dispersed at different wavelengths than the light source. The particular color or wavelength involved with this scatter can help you identify the chemical structure of a substance. This unique scatter is what is known as Raman scatter.

Benefits of Using Raman Spectroscopy

Those who choose to use this application for their analysis requirements can enjoy a variety of advantages, including:

  •    No sample preparation activities are required when using this method, making the entire process shorter than some alternatives.
  •    The results enjoyed with this analysis are highly accurate, as the Raman scatter of a particular molecule can be seen as its chemical fingerprint.
  •    It can be used for long-distance or remote analysis since the laser and scattered light can be transmitted through optical fibers.
  •    Raman analysis works with a variety of substances, including vapors, liquids, and solids.
  •    Unlike some other sensitive means of investigation, Raman analysis is not affected by the presence of water.

Where you choose to buy your spectroscopy system can also play a significant role in the quality you will enjoy with the purchase. It’s crucial to ensure that the provider chosen represents an authentic and reliable distributor. Selecting an established company in this sector for your particular needs enhances your chances of acquiring quality products.

Top Quality and Affordable Solutions for Spectroscopy

The importance of fiber optic spectrometer for scientific applications calls for the necessity of purchasing approved models that will meet all operational requirements.
 
Spectroscopy applications are highly demanding calling for researchers, scientists, and industrialists to go the extra mile and seek top of the line equipment to ease their applications. Primarily, the intent of optical spectroscopy is the measurement of light intensity in NIS, IR, UV, and VIS regions. Increasingly, a large number of applications are dependent on the measurements both within and out of the laboratory. On the larger scale, researchers in photonics and the medical industry have been the top gainers as the niche field advances as time goes by.
 
The general assumption for most people is that for the research and scientific industry, the standards set to dictate each field has resulted in the production of equipment with almost similar working potentials. This could not be further from the truth as different manufacturers and brands utilize their in-house technical and engineering foundation for the productions. As a result, the market is today flooded with thousands of different models with each claiming to offer superior results for the intended application. It has become worse with the rise of model imitations and profit-hungry suppliers who have no limitations when it comes to lack of integrity and business ethics.
 
It, therefore, takes in-depth knowledge and readiness for due-diligence for anyone after laboratory and research equipment especially for demanding applications such as spectroscopy. In the search for a fiber optic spectrometer, the first point of focus must always be on the manufacturer or brand which is a primary determinant of capabilities to expect. Brands that have proved the undying dedication to improving the operational standards for spectroscopy such as Avantes, take away any gambles from the entire process. This is because the manufacturer has spent decades progressively building on their past models and adjusting to the current demands from the science community.
 
Once the manufacturer factor has been taken to account, the next point of emphasis is on the technical specifications of the spectrometer. Even leading manufacturers develop different models to suit all market requirements which translate to the fact there is never a one-size-fits-all solution. Every spectrometer model is designed to suit specific applications with the specifications being the limiting factor to the extent to which a study can be conducted. The core areas to be considered are the grating, slit, and detector which must suit the intended purposes.
 
A final aspect that is never to be ignored is the local supplier one relies on for the completion and delivery of an order. The growth of online shopping has come with its fair share of disadvantages which one must always avoid at all costs. For important purchases such as a spectrometer, the odds are raised and for the avoidance of any potential problems the best option is a registered and certified laboratory equipment supplier. The supplier should have a focus on the niche filed which is spectroscopy and have the professional capacity to respond to all questions and concern. Market reviews and customer service are extra factors to take into account when looking for high-end scientific research solutions.

All you need to Know about a Handheld Raman Spectrometer

A handheld Raman spectrometer is a portable device that is used to identify the material makeup of products with the simple touch of a button.
 

Environments requiring easy and accurate identification methods regarding the materials they come across can purchase a handheld Raman spectrometer. This portable device allows for various onsite applications with relatively simple instructions featured regarding its operation. One simply has to point the device towards the material they want identified and press a button to begin the procedure.
 

How Does the Raman Spectrometer Work?
 

The handheld Raman spectrometer is a portable device with a size similar to a cell phone and weighing about three pounds. It comes with a rechargeable battery that can last up to four hours on the field negating the need for an additional power source. Its software is controlled by a miniature windows operating system that contains the ID-find™ software implemented in the identification process.
 

The material verification procedure features the use of a laser that is emitted from the device’s pointer and directed towards the intended subject. A majority of substances emit a specific light when a laser is shone towards them, and this is known as the Raman scatter effect. This reaction allows the device to identify the unique molecular structure of a substance via comparison on a preset database in its system.
 

Why Use the Raman Spectrometer?
 

The handheld Raman spectrometer is implemented in a variety of settings, including the provision of additional security measures and chemical identification. This device has simplified the process required for such verification as it does not need contact with the material inspected. The device’s operating system can also pull up relevant data regarding the information acquired in a matter of seconds.
 

The application of laser illumination techniques also means that this process is applicable via transparent packaging such as plastic or glass. Thus delicate products do not have to be unnecessarily exposed to the environment during material verification. Its portability also adds the benefit of enhanced flexibility when working the Portable-PinPointer™.
 

The extensive database provided within the operating system also means that a user does not have to retain any chemical knowledge to operate the device. Once the pointer has been directed towards the subject, it will compare the information received with a collection of numerous other results in its database. Once it finds a matching solution, the results will then be transmitted to the user, limiting the overall amount of work involved on their part.
 

Chemical Databases
 

Individuals who purchase this product from a reliable provider will also enjoy an additional database containing thousands of chemical comparisons already set into the system. Clients who work in a unique environment and do not come across regular comparisons can purchase specialized databases as well. Those who would rather customize the collection process on their own can scan known elements and input the spectra into the system.
 

The chemical spectra scanned when creating a customized database is an important issue to consider as it can affect the accuracy of one’s operations. Saving the wrong information about a spectrum, for example, will lead to the delivery of inaccurate results in the future.

Affordable Microscopes for Everyday Use in Singapore

Microscopes are must-have equipment for any scientist involved in research especially in the fields of biology, medicine, and chemistry. The most popular microscope models are now available from local distributors in Singapore as cost-effective rates.

 

In every laboratory setting, microscopes take center stage as they are the primary equipment through which scientists are able to make explorations beyond levels which the human eye can allow. Right from early stages when students are introduced to the essential elements of life sciences to when they become seasoned professionals, microscopes are items which are unavoidable for any worthwhile project. It is therefore rightly called for that there is a great diversity of microscopes that are currently available in the market as needs at different levels have been adequately catered for by top-rated manufacturers.

 

The growth of e-commerce has made it easier to acquire a microscope in Singapore without the burden of having to physically locate a laboratory supplies store. All the benefits that the internet has brought to the science community have come with equal measures of limitations more so when it comes to making genuine purchases. A simple strategy that has proven to be highly efficient and practical for professionals after research products have been to avoid general stores and stick to companies that are focused on their niche-segments.

 

Imitations are the order of the day, and when looking for microscopy solutions, it is easy to fall victim of fake brands which many resellers can easily give you at a tenth of the original price. The necessity for affordability must be balanced with the non-substitutable benefits of quality which is precisely what a distributor focused in the research community provides. All benefits of high magnification capacities and optical quality in microscopes come at a price which cannot be obtained through an offer made by a store that lacks understanding of the demands by professionals and students in varied sectors.

 

When looking for a microscope in Singapore, you also need a team that will provide you with more than a product but offers a whole line of complementary services and maintenance. Resellers lack the understanding of the build and design of different microscopes and only look to take advantage of their capacities to serve each industry. On the other hand, a store whose expertise is in laboratory products and accessories has the much-needed skilled workforce that enables them to give you a full package that covers post-sales services. You, therefore, do not have to worry about any needs that might arise from the use of the products as instant solutions will be a call away.

 

Beyond microscopy demands, the research community has a full line of product requirements which must be addressed from time to time. Online stores with a focus on laboratory solutions will provide you with more than an inventory of microscopes but packages which cater to varied fields of study. These categories can include among other spectroscopy, bio-medical equipment, terahertz technology, and laser & light sources. The strong support role that stores dedicated to the progress of the rapidly rising science research sector in Singapore exceeds any alternatives that might have been brought with the increased commercialization of the internet.

A Brief Guide: What You Need to Know About Spatial Light Modulator

A spatial light modulator refers to objects that are being used to produce a radiating beam of light with various modifications. The most common type of spatial light modulator is the LCOS spatial light modulator that is being used in various laser material processing, quantum optics, and microscopy. LCOS stands for liquid crystal on silicon, and literally this is how it brings about the image display. Simple light modulators serve a great deal of importance in our world today as they are being used mostly in overhead projectors, holography, and optical industry in general. Also, they can be used for signage and brand advertisement in cities around the world.

Other Types of Spatial Light Modulator

LCOS isn’t the only type of spatial modulator that we see in the market, as there are other types that serve important functions just like LCOS. They include:

Electrically Addressed Spatial Light Modulator

Just like the image of LCOS modulator is being changed by the liquid crystal on the silicon, that of the electrically addressed modulator is being changed electronically. The displays are also electronic displays, and unlike other types of spatial light modulator, the displays are smaller and cannot be viewed directly. A typical example of an electrically addressed spatial light modulator is the digital micro mirror device.

Optically Addressed Spatial Light Modulator

This type of modulator makes use of a light source to reflect its images. Liquid crystals are also being used to make a semblance of the image after the photosensor might have sensed the light brightness. But as long as this spatial light modulator is still powered electrically, it would not lose the image, not even after the bright light might have disappeared. They are being used in holographic displays, and there can also be the transfer of images from the electrical spatial modulator to this modulator.Images on display with optically addressed spatial modulators usually have more quality and resolution.

Value of Spatial Light Modulators

The market for spatial light modulators had initially gone under the radar, and this is probably due to the fact that not a lot of people possess the technical know-how on how to operate it. According to market research, the value for spatial light modulator is predicted to grow by more than 100% in the next few years. This is due to the importance, and the awareness that it is garnering these days. Another reason is that it has been noted that in past years, spatial light modulators were not known to perform some of the functions that they perform these days. So with this, a lot of people are expecting that with the improvement of technology, there will be more functions that a spatial light modulator can serve.

Also, another feature of a spatial light modulator that has brought about its increase in value is the beam shaping segment. It can be used for lasers, material processing, as well as pulse shaping. This has made it important in a lot of industries, hence leading to the high demand for spatial light modulators.

You can purchase LCOS spatial light modulators and other types online, by searching for the website of sellers through the use of search engines.
