Optical Port Dimensions for HSDL-3021
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°.
