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. If the window
must be curved for mechanical or
industrial design reasons, place
the same curve on the backside 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 significantly 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.
Flat Window
(First Choice)
Curved Front, Flat Back
(Do not use)
Curved Front and Back
(Second Choice)
