摘要：An optical encoder apparatus is disclosed comprising a light source, a lens forfocusing and collimating light emitted from the light source, a cap for receiving andaligning the light source and the lens, a scale movable relative to the cap includingalternating opaque and translucent regions for blocking and transmitting light emittedfrom the light source, an array of a plurality of photodiodes for converting light emittedfrom the light source into electrical signals, a mask mounted in a fixed position betweenthe scale and the photo transducer array, including in the mask alternating opaque andtranslucent regions arranged to act in concert with the movable scale to modulate thelight received by the photo transducers, a mounting post for mounting the opticalencoder apparatus, a receptor for attaching to the cap including a deck for receiving andaligning the photo transducer array, and including a cavity for receiving the mountingpost, and a clamp for securing the receptor, and therefore the optical encoder

apparatus, to the mounting post. The method for manufacturing the encoder apparatusis also disclosed and claimed.
