Appendix D: Optical Port Dimensions for HSDL-3602:
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 mini-
mize the effects of stray light. The minimum size cor-
responds to a cone angle of 30
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-3602 to 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 com-
puting 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
where ‘t’ is the thickness of the window and ‘n’ is the re-
fractive index of the window material.
