||| |||

Combining exceptional quantum efficiency with high speed communication is the value proposition of the AvaSpec-ULS2048XL EVO spectrometer. Unlike many back-thinned CCD spectrometers that have two dimensional arrays, the ULS2048XL-EVO has large monolithic pixels of 14x500 microns with exceptional efficiency in the UV range, from 200 to 400 nm, and the NIR range, from 950 to 1160 nm. The instrument also has an electronic shutter, which enables integration times as low as 2 microseconds. To further enhance sensitivity, a detector collection lens is available, which improves sensitivity up to 60% when combined with larger core fibers.
