High Temp Window propeine 5/21/2004
Any suggestions on a high temp window to protect my A20? I was thinking ZnSe but supposedly it isn't usable much over 300C and my furnace is running at 1200-2000F.

ZnSe has a melting point of 1525 C. However, to use it at these extreme temperatures, you need to have it AR coated on both sides.

Where did you hear it was not usable over 300 C?
