AvaSpec-HS2048XL-EVO SensLine High UV and NIR Sensitivity Back-thinned CCD Spectrometer 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 AvaSpecHS2048XL has a back-thinned CCD detector with 2048 pixels measuring 14X500 microns. able. The AvaSpec-HS2048XL is available with a wide range of slit sizes, gratings and may be configured with SMA or FC/ PC fiberoptic entrance connectors. The AvaSpec-HS2048XL-EVO uses the AS7010 electronics board offering USB3 (10 times faster than USB2), Gigabit Ethernet and better signal processing. Unlike many back-thinned CCD spectrometers, which have two dimensional arrays the HS2048XL has large monolithic pixels with exceptional efficiency in the UV, from 200-400 nm, and the NIR, from 950-1160 nm, while retaining sensitivity in the visible range. The unique optical design features torroid collimating and focusing mirrors to control image magnification and enhance efficiency. The instrument also features an electronic shutter, which enables integration times as low as 2 microseconds. For configurations, which require second order filtering, order-sorting filters are avail- Technical Data Optical Bench Wavelength range High-sensitivity asymmetrical design, 37.5 mm focal length; NA – 0.22, f/2.27 200 - 1160 nm 1 - 20 nm, depending on configuration (see table) UV Quantum efficiency Detector 60% (200-300 nm) Back-thinned CCD image sensor 2048 pixels Integration time Interface Sample speed with on-board averaging Dynamic Range Data transfer speed Digital IO Power supply Dimensions, weight 2 µs – 600 seconds USB 3.0 high-speed, 5 Gbps Gigabit Ethernet, 1 Gbps 2.44 ms /scan 14.900 2.44 ms /scan (USB3) HD-26 connector, 2 Analog in, 2 Analog out, 3 Digital in, 12 Digital out, trigger, synchronization Default USB power, 700 mA. or external 12VDC, 360 mA 175 x 165 x 85 mm, 1,950 kg
