AvaSpec spectrometer components can also be provided as separate products to be used in OEM applications. Avantes has developed 3 types of UV/VIS optical benches, special for OEM customers.
The optical benches AvaBench-45, AvaBench-75-ULS 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 200-1100nm range. The newly designed AvaBench-USL has full mechanical compatibility for mounting holes with the AvaBench-75, so for OEM customers it is easy to upgrade to the better ULS optical bench.
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 for these AvaBenches is -U2.
