AvaSpec-ULS2048x64TEC-EVO Cooled Fibre-Optic Spectrometer
Overview
AvaSpec-ULS2048x64TEC-EVO: ultra-low stray-light ULS optical bench (75mm) with 2048×64 backthinned low-noise CCD and integrated Peltier cooling (chip to -30°C vs ambient), integration up to 120s; excellent UV/IR sensitivity, dark noise 5 counts, ideal for fluorescence and low-light Raman.Description
【Overview】
The AvaSpec-ULS2048x64TEC-EVO is a cooled fibre-optic spectrometer of the Avantes SensLine series, featuring the ultra-low stray-light ULS bench (75mm) and a 2048×64 backthinned low-noise CCD.
【Key Features】
(1) ULS ultra-low stray-light bench, 75mm focal length;
(2) 2048×64 backthinned CCD, excellent UV/IR sensitivity, 64-row pixel height (0.89mm) for photon collection;
(3) Integrated Peltier cooling to -30°C vs ambient, improving dark baseline, dark noise reduced 2-3x;
(4) Integration up to 120s, dark noise only 5 counts;
(5) USB3.0 + Gigabit Ethernet, replaceable slit;
(6) Ideal for low-light applications requiring more than 5s integration.
【Typical Applications】
Fluorescence, low-light Raman, weak-signal spectroscopy, UV/IR spectral analysis.
