For high-sensitivity applications where high resolution is not of paramount concern, the AvaSpec-HS2048XL-EVO is an exceptional instrument.
Featuring Avantes’ HS optical bench, which has a full 0.22 numerical aperture for superior throughput, the AvaSpec-HS2048XL has a back-thinned CCD detector with 2048 pixels measuring 14×500 microns.
The AvaSpec-HS2048XL-EVO uses our AS-7010 electronics board offering USB3 (10 times faster than USB2), Gigabit Ethernet and better signal processing.
