For module depth values that are
not shown on the table above, the
minimum X and Y values can be
interpolated. An example of this
interpolation for module depth of
0.8 mm is as follows:
X
Y
Window Material
Almost any plastic material will
work as a window material.
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

Lexan 141
Lexan 920A
Lexan 940A
Note: 920A and 940A are more flame retardant than 141.
Recommended Dye: Violet #21051 (IR transmissant above 625 nm)
