Conventional modulated infrared LED photoelectric emitters are designed with beam
divergence angles of several degrees. As a result, most emitters are easily aligned to their
receivers by simple line-of-sight methods.
The beam widths listed in Figure 1 are also the effective beam sizes at the receiver for model
QS186LE. The effective beam size is equal to the minimum opaque object profile required to
block the laser beam. The beam size at the emitter is 2.5 mm (0.1") diameter. Beam sizes at
various distances for other models are shown in the tables below.
The effect of angular misalignment is dramatic (see Figure 3). The wide beam angles offered
by conventional photoelectric emitters allow several degrees of misalignment between the
optical axes of the emitter and receiver. This is not true for laser emitters, which require the
beam center to directly strike the receiver lens. Figure 3 shows how far the laser beam will
miss the center of the receiver lens for one degree of angular misalignment (in any plane).
Note that even at a 5' range, one degree of misalignment will cause the laser beam to miss
the lens of most receivers.
