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
0
and the maximum size
corresponds to a cone angle of
60
o
.
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-3612 to
Appendix C: Optical Port
Dimensions for HSDL-3612:
the back of the window. The
distance from the center of the
LED lens to the center of the
photodiode lens, K, is 7.08mm.
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-3612, D, is
8mm. ‘A’ is the required half
angle for viewing. For IrDA
compliance, the minimum is 15
0
and the maximum is 30
0
.
Assuming the thickness of the
window to be negligible, the
equations result in the following
tables and graphs:
