Appendix D : Window Designs
for HSDL-3002
Optical port dimensions for
HSDL-3002
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
°
and the maximum size
corresponds to a cone angle
of 60
°
.
In the figure below, X is the width
of the window, Y is the height of
the window and Z is the distance
from the HSDL-3002 to the back
of the window. The distance from
the center of the LED lens to the
center of the photodiode lens, K,
is 5.8 mm. The equations for
computing the window
dimensions are as follows:
X = K + 2*(Z+D)*tanA
Y = 2*(Z+D)*tanA
The above equations assume that
the thickness of the window is
negligible compared to the
distance of the module from the
back of the window (Z). If they
are comparable, Z' replaces Z in
the above equation. Z' is defined as
Z' = Z+t/n
where ‘t’ is the thickness of the
window and ‘n’ is the refractive
index of the window material.
The depth of the LED image
inside the HSDL-3002, D, is
8.6 mm. ‘A’ is the required half
angle for viewing. For IrDA
compliance, the minimum is 15
°
and the maximum is 30
°
.
Assuming the thickness of the
window to be negligible, the
equations result in the following
tables and graphs:
