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