what is good glass to use for projector's aperture window?

EDIT: The way some of the members here have desperately tried to identify my location and nationality for whatever reason they believed was needed for by asking an admin to check my profile logs and researching me by the content of my posts has been very creepy and unnecessary. So bye.

A quick and easy way to find it local is Museum Glass from the Picture Frame Shop. They can usually cut it for you as well.

You won't need low iron. Nobody will AR coat visibly greenish glass which has iron in it.

The best AR coats are multilayer AR coats. You do want that instead of a 1/4th wavelength "V" coat if you can get it.

0.5% is typical for a low cost coating these days.

Gotta jet, but quick Info-post / curves / real-world suggestion for how / why to 'rake' / eliminate 'scan-mirror ghosting', etc, etc.. http://www.photonlexicon.com/forums/...757#post220757

..Also, Edmunds "VIS-0" is the best for 400-700, at 0˚ 'AOI', even better than the 'CDAR', but also more $$, and avail. in less-sizes (as 'stock items'..) than the CDAR..
