Shape of the Window
From an optics standpoint, the window should be flat.
This ensures that the window will not alter either the ra-
diation pattern of the LED, or the receive pattern of the
photodiode.
If the window must be curved for mechanical design rea-
sons, place a curve on the back side of the window that
has the same radius as the front side. While this will not
completely eliminate the lens effect of the front curved
surface, it will 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.
