    Hello,
    Our team are interested in two products of your company,they are STT-3200ME and ST-3200ME.

    We need some parameters about STT-3200ME and ST-3200ME now.We want know the distance between

    the sealed windows glass and CCD surface.And we want know the thickness of the sealed windows

    glass.Thank you for your help!

    Dear Mr. Doug
    Our team are designing an astronomical telescope. We’d like to use STT3200ME as our guide star camera. You’ve given us
    the backfocus distance last time, thank you very much! And we need more help. We want know the window glass thickness
    and the distance between windows glass and CCD surface. And we want know the refractive index of the window glass too.
    These parameters are very important for the design of our optical platform. We will be very appreciated if you can help.

    It's a sapphire window. You can look up the properties. Thickness is 0.039"

    Dear Mr. Doug:
    Thank you for telling me the thickness of the windows glass.And as I've asked last time,we want know the distance between windows glass
    and CCD image plane , just like the picture above.This parameter is very important for the design of our optical platform. We will be very appreciated if you can help.

    Doug - the backfocus table doesn't list this camera, although its probably like the STF-8050, which has a backfocus of 17.2mm without filters or nosepiece.

    He's asking about the STT series. The backfocus numbers in the table should be accurate.

    Distance from the back of the chamber window to the KAF-3200 CCD window (not the image plane) is approximately 2.4 mm.
