WINDOW

To ensure IrDA compliance, some constraints on the

height and width of the window exist. The minimum

dimensions ensure that the IrDA cones angles are met

without vignetting. The maximum dimensions minimize

the effects of stray light. The minimum size corresponds

to a cone angle of 300 and the maximum size corre-

sponds to a cone angle of 600.

In the figure above, X is the width of the window, Y is the

height of window, Z is the distance from the ASDL-3023

to the back of the window and T is the thickness of the IR

transparent window.

W = 0.3456*T, W2 = 0.6967*T, where T is the window

thickness

For the modules depth values that are not shown on the

tables above, the minimum X and Y values can be inter-

polated.
