Appendix B: HSDL-3000#007/#017 – Recommended Optical Port Design
To insure IrDA compliance, some constraints on the
height and width of the window exist. The minimum di-
mensions ensure that the IrDA cone angles are met with-
out vignetting. The maximum dimensions minimize the
effects of stray light. The minimum size corresponds to a
cone angle of 30 degrees, the maximum, to a cone angle
of 60 degrees.
X is the width of the window, Y is the height of the win-
dow, and Z is the distance from the HSDL-3000 to the
back of the window.
The distance from the center of the LED lens to the cen-
ter of the photodiode lens is 5.80 mm. The equations for
the size of the
X = 5.80 +2(Z + D) tan θ
Y = 2(Z + D) tan θ
Where θ is the required half angle for viewing. For the
IrDA minimum, it is 15 degrees, for the IrDA maximum it
is 30 degrees. (D is the depth of the LED image inside the
part, 3.2 mm from the Tx lens vertex). These equations
result in the following tables and graphs:
