I need help in understanding the purpose of the cover glass on CCD's other than as a dust shield and for protection. I was told the cover glass also acts as an NIR filter above 700nm to avoid saturation. Is this correct? Also, I am planning to mount a graded filter as close to the focal plane of a B/W CCD sensor as possible and would like some comments on how successful I might be in removing the cover glass? Any clues in improving my chance of success? Thanks.

The cover glass directly on the sensor is for protecting the sensor. It has no IR Cut capabilities.

We do not recommend to remove the sensor glass. Usually you destroy the sensor doing so.

Thanks Stefan for your speedy response. I will resist the temptation to mess with the coverslip.
