What types of windows can I choose from for my detector?
Our supplier VIGO offers thermoelectrically cooled detectors which are typically provided with:
- 3° wedged Al2O3 windows (wAl2O3)
- 3° wedged ZnSe AR coated windows (wZnSeAR)
3° wedge prevents “fringing” – interference from stray back reflections and there is also windows optimized for different spectral bands. Windows can be anti-reflection (AR) coated on two surfaces. We can mount windows provided by the user as well as filters.
VIGO has summarized their detector windows in the figure below.Source (with permission to reproduce): https://vigo.com.pl/en/support/faq/
