Question/Comment: 

Entrance window should be wedged and AR coating?
Would this degrade optical performance?


Submitted by: Bruce Gillespie


NIC-FPS Response:

The window would be AR coating. The amount of wedge will have to be
balanced between reducing of ghost images and dispersion.

Recommneded materials are fused silica and CaF2.
