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 should be 10 percent or less for best optical
performance. Light loss should be measured at 875 nm.
Shape of the Window
From an optics standpoint, the window should be flat.
This ensures that the window will not alter either the
radiation pattern of the LED, or the receive pattern of
the photodiode.

Flat Window

Curved Front and Back
(Second choice)

HSDL-3602 Curved Window
If the window must be curved for mechanical or in-
dustrial design reasons, place the same curve on the
back side of the window that has an identical radius as
the front side. While this will not completely eliminate
the lens effect of the front curved surface, it will sig-
nificantly reduce the effects. The amount of change in
the radiation pattern is dependent upon the material
chosen for the window, the radius of the front and back
curves, and the distance from the back surface to the
transceiver. Once these items are known, a lens design
can be made which will eliminate the effect of the front
surface curve.
The following drawings show the effects of a curved
window on the radiation pattern. In all cases, the center
thickness of the window is 1.5 mm, the window is made
of polycarbonate plastic, and the distance from the
transceiver to the back surface of the window is 3 mm.
