Can anyone identify this diode? It has a plastic case which is white, a gold plate on the bottom. The yellow lines are where it almost looks like it plugs into something. The 2 red things look to be the diodes, but the little gold square beside the crystal in light blue also looks to be a diode with a small wire going down to the gold stripe, like a c-mount laser. The green is around a L shaped crystal and the 2 purple stripes are where the crystal looks like it directs the beam in the direction the purple lines are going. Anyway, I have 4 of these and was just curious what they are.
