I have a proximity sensor that consists of and emitter and photo-transistor that are very small. The emitter and photo-transistor are in sockets and need lens covers over them. The lens covers are circular, approximately 5mm (outer diameter) and perhaps 1mm thick and are violet in color. I am having a tough time finding a source for lenses this small. I also gave thought to having them machined from a larger sheet of violet glass/plastic but would like to find the lens already made, if possible. Does anyone have any ideas on who might have such an item?
Thanks
