AvaSpec NIR spectrometer components can also be provided as separate products to be used in OEM applications. Avantes has developed different types of NIR optical benches, special for OEM customers. The optical bench AvaBench-50 is available in the 1000-1750nm range for uncooled detectors. The AvaBench-50TEC is developed for NIR range from 1000-2500nm. The AvaBench-50TEC supports 3 different TE cooled detectors with 256 pixels. They are all symmetrical Czerny-Turner designs with fiber optic entrance connector (Standard SMA, others possible), collimating and a newly designed special toroid focussing mirror and diffractional grating. A choice of different NIR gratings can be selected with the products. Wavelength ranges, resolution tables, detector specifications and AvaBench options can be found in the sections on the AvaSpec products.In the table below the main differences between the optical benches are pointed out.The NIR AvaBenches can only be connected to the USB2 platform electronics (AS-5216 boards) and have a separate video output through a mini-coax cable. The TEC NIR benches have a heatsink and additional electrical connections for both Temperature sensor and power for the 2-stage Peltier cooling.
