ABSTRACT:
A method for producing opto-electronic devices, such as opto-mechanical mouse devices, which includes adjusting a detector signal after a detector and emitter are connected to the remaining circuitry associated with the opto-electronic device. The method also includes a rough adjustment step wherein a the detector signal is adjusted to a predetermined output voltage, and a fine adjustment step wherein an encoder is rotated between the emitter and the detector, and the circuit is adjusted such that the duty cycle of a comparator is within a desired range.
