Window Material
Almost any plastic material will work as a window mate-
rial. Polycarbonate is recommended. The surface finish
of the plastic should be smooth, without any texture. An
IR filter dye may be used in the window to make it look
black to the eye, but the total optical loss of the window
Recommended Plastic Materials:

Lexan 141
Lexan 920A
Lexan 940A
Note: 920A and 940A are more flame retardant than 141.

should be 10% or less for best optical performance.
Light loss should be measured at 875 nm. The recom-
mended plastic materials for use as a cosmetic window
are available from General Electric Plastics.
