Window Designs for
HSDL-3005
To ensure IrDA compliance,
some constraints on the height
and width of the window exist.
The minimum dimensions
ensure that the IrDA cone angles
are met without vignetting. The
maximum dimensions minimize
the effects of stray light. The
minimum size corresponds to a
cone angle of 30 degrees, the
maximum to a cone angle of 60
degrees.
X is the width of the window, Y
is the height of the window, and
Z is the distance from the HSDL-
3005 to the back of the window.
The distance from the center of
the LED lens to the center of the
photodiode lens is 5.1 mm. The
equations for the size of the
window are as follows:
Where
angle for viewing. For the IrDA
minimum, it is 15 degrees, for
the IrDA maximum it is 30
degrees. (D is the depth of the
LED image inside the part, 3.17
mm). These equations result in
the following tables and graphs:
