Abstract
An optical analog potential apparatus comprises a circuit board, an emitter module, a receiver module and a controller. The circuit board has a light emitting assembly; and the emitter module is arranged on the circuit board and has a light guide with a bevel. The receiver module is arranged on the circuit board and has a lens connected to an optoelectronic element. The controller is arranged between the emitter module and the receiver module. The light received by the receiver module is controlled by the controller to provide output of various levels.
