An optical encoder includes an encoder pattern having (i) an A/B pattern of first areas and second areas alternating in a first direction, wherein the first areas have a different optical transmissivity or reflectivity than the second areas, and (ii) an index pattern disposed adjacent the A/B pattern in the first direction.

Optical encoder with integrated index channel

Optical encoders having one or more of a number of disclosed features are disclosed. The features of the optical encoder in accordance with the present invention include a symmetrical (for example, circular) emitter; baffle between the emitter and a detector; double-dome or single-dome encapsulant; multiple detector; and multiple (at least three) data channels.
