    Hello

    Does ST-402 have a window or a filter in front of sensor? If yes, how much is thickness? I'm using ST-402 to do spectroscopy by combining with our own grating. However, obtained spectra had a periodic signal which looks like an interference pattern caused by a thin window. So, I'm wondering if ST-402 has a window or a filter.

    Yes, there is a window on the sensor itself, and one on the chamber.

    Yes, the CAD drawing says 0.125", which is just over 3 mm.
