In the figure above, 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, K,
is 5.1mm. 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,
W1 = 0.33*T,
W2 = 0.66*T,
where T is the window thickness and the refractive index of the window material is 1.586.
The depth of the LED image inside the HSDL-3021, D, is 3.17mm. ‘A’ is the required half angle for viewing. For IrDA
compliance, the minimum is 15° and the maximum is 30°. The equations result in the following tables and graphs. The
graphs are plotted assuming that the thickness of the window is negligible.
It is recommended that the tolerance for assembly be considered as well. The recommended minimum window size
which will take into account of the assembly tolerance is defined as:
Xmin + assembly tolerance = Xmin + 2*(assembly tolerance) (Dimensions are in mm)
Ymin + assembly tolerance = Ymin + 2*(assembly tolerance) (Dimensions are in mm)
