Combining exceptional quantum efficiency with high speed is the value proposition of the AvaSpec-ULS2048XL spectrometer.

Unlike many back-thinned CCD spectrometers which have two dimensional arrays, the AvaSpec-ULS2048XL has large monolithic pixels of 14x500 microns with exceptional efficiency in the UV from 200-400nm and the NIR from 950-1160nm. 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 fibres.

Multiple options include order sorting filters to reduce 2nd order effects, and purge ports for deep UV measurements. The AvaSpec-ULS2048XL comes with a wide range of slit sizes, gratings and may be configured with SMA or FC/PC fibre optic entrance connectors.

Connection to your PC is handled via a USB3 connection, delivering a scan every 2.44 milliseconds. The instrument comes complete with AvaSoft-Basic software, USB cable and an extensive manual, including a quick start guide in four languages.
