The NEXOSTM is a next-generation photonics backbone spectrometer enhancing numerous applications across multiple sectors. The most recent automation techniques from Avantes are used in the production of this device to guarantee excellent inter-instrument repeatability.
Compact Size, Limitless Possibilities
The powerful and lightweight NEXOSTM spectrometer from Avantes provides top-notch performance for spectroscopy integration. With integration durations of up to 9 μs, minimum stray light as low as 0.1%, and an excellent signal-to-noise ratio of 375:1, the spectrometer offers high-speed performance.
Avantes light sources, accessories, and AvaSoft software are all compatible with the NEXOSTM, allowing customers to tailor their setups to specific measuring needs.
This robust and adaptable spectrometer features USB2 connectivity. There are additional communication protocols (such RS232/SPI) that are tailored for Original Equipment Manufacturer (OEM) uses.
With over 15 types of gratings and six slit diameters, this device can be tailorored to exact specifications. For non-OEM products, the replacement slit option is standard.
The spectroscopic device can be used in conjunction with Software Development Kits (AvaSoft) and is ideal for OEM applications.
Avantes can create large quantities of the NEXOSTM spectrometer with exceptional accuracy and repeatability at a faster efficiency rate due to the manufacturing process's automation.
Product Variations
Avantes also introduces the NEXOSTM-Link and NEXOSTM-Bench Only in addition to the USB-powered NEXOSTM. For OEM clients, the Link version provides alternative communication protocols (RS232 or SPI). The Bench Only version is designed for easy implementation on either the Avantes AS7010 electronic board or the customer's own electronic board.
