Window Design
To insure IrDA compliance, there
are some constraints on the
height and width of the optical
window. The minimum
dimensions ensure that the IrDA
cone angles are met, and there is
no vignetting, and the maximum
dimensions ensure that the effects
of stray light are minimized. The
minimum size corresponds to a
cone angle of 30 degrees, the
maximum to a cone angle of 60
degrees.
The drawing below shows the
module positioned in front of a
window.
X is the width of the window, Y is
the height of the window, and Z is
the distance from the HSDL-3021
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 that determine the
size of the window are as follows:
X = 5.1 + 2(Z + D) tan
q
Y = 2(Z + D) tan
q
Where
q
is the required half 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:
