AvaSpec spectrometer components can also be provided as separate products to be used in OEM applications. Avantes has developed 3 types of optical benches, special for OEM customers.
The optical benches AvaBench-45, AvaBench-50 and AvaBench-75 are symmetrical Czerny-Turner designs with fiber optic entrance connector (Standard SMA, others possible), collimating and focussing mirror and diffractional grating. A choice of different gratings with different dispersion and blaze angels enable applications in the 200-2500nm range.
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 AvaBenches to be connected to the USB2 platform electronics (AS-5216 boards) have a separate video output through a mini-coax cable. The order code on these AvaBenches is -U2.
