Compact, Economical, High Brightness,Broadband Laser-Driven Light Source

EQ-99X LDLS Laser-Driven Light Source

The compact LDLS EQ-99X is an ultra-high brightness, high stability broadband source that is specifically designed for demanding imaging and spectroscopy applications. The EQ-99X offers excellent spatial and power stability for highly repeatable measurements across the broad spectrum.

Utilizing a patented laser-driven bulb technology* the EQ-99X is ideal for applications requiring ultra-long lamp life. The EQ-99X is available with a range of free-space broadband reflective coupling optics to match the ~100µm plasma size to the customers instrument or application. With its high brightness, small plasma, the EQ-99X is particularly well suited to applications using narrow spectrometer slits, small diameter optical fibers or other small étendue optics.

High Brightness, Broadband Light Source with Fiber-Coupled Output

EQ-99XFC LDLS Laser-Driven Light Source

Advanced imaging & analytical spectroscopy applications in the life sciences and materials sciences need light sources capable of providing extremely high brightness across a broad wavelength range. Traditionally, multiple lamps (Halogen/Tungsten, Xenon-arc, Deuterium) have been used to cover this broad spectral range. However, combining multiple lamps is costly and optically inefficient, and the use of electrodes within these lamps limits their ability to achieve the high brightness or power needed for the most demanding applications. Furthermore, traditional electrode-driven light sources have short life, need to be changed frequently, and during their life the lamp output declines constantly. To address these problems, Energetiq has developed a revolutionary single-light source technology called the LDLS™ Laser-Driven Light Source that enables extreme high brightness with a relatively flat spectrum, from deep ultraviolet through visible into the near infrared, combined with life-time an order of magnitude longer than traditional lamps.

The LDLS EQ-99XFC has integrated collection optics that allow greater ease of use for those needing a fiber connection. The high performance ellipsoidal collector ensures that the ultra-high brightness light and power stability are maintained across the broad spectrum, from 190nm to 2100nm, and efficiently coupled into small diameter optical fibers. Proprietary Fiber-Protection Technology™ enhances DUV performance and significantly extends fiber life by reducing the effects of solarization. Utilizing a patented laser-driven bulb technology* and ultra-clean construction, the EQ-99XFC is ideal for applications requiring ultra-long lamp life combined with high broadband brightness.

Broadband Light, High Brightness, Calibration Source

EQ-99CAL Broadband, High Brightness Calibration Source

Traditional calibration sources for radiometric calibration, such as Deuterium, Quartz Tungsten Halogen, and Xenon-arc, all have limitations in spectral range. No one source covers the full UV-Visible range from 200nm-800nm with output at comparable levels across that spectrum. In addition, traditional sources require recalibration after 100 hours or less of use and lamp replacement typically after 500 hours. With its revolutionary Laser-Driven Light Source™ (LDLS), Energetiq offers a calibration solution that addresses these limitations and provides a single, broadband, high brightness source for radiometric calibration.
The EQ-99CAL combines radiometric performance with long life, longer recalibration intervals, and low cost of ownership. Calibrations made in the 350nm range are particularly challenging with Deuterium and Quartz Tungsten Halogen lamps. In the case of Deuterium lamps at 350nm, the irradiance is approximately an order of magnitude lower than its value in the deep UV at 200nm. Similarly, Quartz Tungsten Halogen lamps at 350nm are more than an order of magnitude lower in irradiance compared to their value in the visible range. Additionally, it is frequently problematic to have the two separately calibrated lamps agree at the overlapping wavelengths, adding additional uncertainty. With the LDLS, a single calibrated light source covers the whole range from 200nm to 800nm, and at 350nm exhibits an irradiance an order of magnitude higher than traditional calibrated Deuterium and Quartz Tungsten Halogen lamps.
Energetiq’s EQ-99CAL product is calibrated at our calibration partner, Bentham Instruments, Ltd. Bentham’s calibration standards are traceable to the National Physical Laboratory (UK). A certificate of calibration, which comprises the calibration data and the uncertainty analysis, is included with each EQ-99CAL. Sample calibration reports are available upon request.
