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 14×500 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 fibres. Optical bench - Ultra-low stray light (ULS) symmetrical Czerny-Turner, 75 mm focal length Resolution - 0.09-20 nm, depending on configuration Stray light - <0.5% Sensitivity in counts/µW per ms integration time - 460,000 UV quantum efficiency - 60% (200-300 nm) Detector - Back-thinned CCD image sensor, 2048 pixels Signal/noise - 525:1 AD converter - 16 bit, 1 mHz Integration time - 2 µs-20 sec Interface - USB 3.0 high speed, 5 Gbps, Gigabit Ethernet 1 Gbps Sample speed with store to RAM - 2.44 ms/scan Readout noise - 9.8 cnts RMS Dark noise - 4.5 cnts RMS Dynamic range - 13,700 Data transfer speed - 2.44 ms/scan (USB3) Digital IO - HD-26 connector, 2 Analog in, 2 Analog out, 3 Digital in, 12 Digital out, trigger, synchronization Power supply - Default USB power, 700 mA Or external 12VDC, 360 mA Dimensions, weight - 175 x 127 x 44,5 mm (1 channel), 1180 g
