Recommended Plastic Materials:
Material #
Lexan 141
Lexan 920A
Lexan 940A
Note: 920A and 940A are more flame retardant than 141.
Recommended Dye: Violet #21051 (IR transmissant above 625 mm)
For the modules depth values
that are not shown on the tables
above, the minimum X and Y
values can be interpolated.
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

should be 10% or less for best
optical performance. Light loss
should be measured at 875 nm.
