ABSTRACT:
A high isolation voltage optocoupler includes spaced apart emitter and detector elements coupled to one and the other ends of a bar of light transmissive dielectric material. A reflective coating on the surface of the bar enhances light coupling. An opaque dielectric housing excludes ambient light and provides mechanical support for the coupling elements.
