Meet the NEXOS™, the next-generation photonics backbone spectrometer designed to empower a wide range of applications in various industries. This device is manufactured with Avantes’ newest automation techniques to ensure superior inter-instrument reproducibility. Discover how this innovative spectroscopy instrument will empower your application!
Compact Size, Limitless Possibilities
Avantes’ NEXOS™ is a lightweight, and powerful spectrometer optimized to deliver high-end performance for spectroscopy integration. The spectrometer offers high-speed performance, with integration times of up to 9 μs, minimal stray light as low as 0.1%, and a strong signal-to-noise ratio of 375:1.
The NEXOS™ is compatible with Avantes light sources, accessories, and AvaSoft software, enabling users to customize their setups to suit their measurement requirements.
This powerful and versatile spectrometer is available with USB2 communication. Other communication protocols (e.g., RS232/SPI) optimized for Original Equipment Manufacturer (OEM) applications are also available. This device can be customized to your needs using six different slit sizes and more than 15 types of gratings. The replaceable slit option is standard for Non-OEM.
This spectroscopy instrument is highly suitable for OEM applications and can be combined with our Software Development Kits (AvaSoft). Thanks to the automation of our manufacturing process, Avantes can produce high volumes of the NEXOS™ spectrometer more efficiently and faster with very high accuracy and reproducibility.
Products Variations
Besides the USB-powered NEXOS™, we also introduce the NEXOS™-Link and NEXOS™-Bench Only. The Link version offers different communication protocols for OEM customers (RS232 or SPI). The Bench Only version is optimized for easy implementation on the customer’s own electronic board – or Avantes’ AS7010 electronic board.
