OPTICAL SIGHT

摘要

An optical sight comprises an elongate housing defining a light channel. A lens is provided at one end of the light channel and has a partially reflecting surface. A laser diode is energised by a pulsating electric current delivered by a battery powered energising circuit, and the energised laser diode emits light towards the reflecting surface to produce a light spot by direct imaging of the laser diode on the surface. The light spot shall be superimposed on the target when sighting through the light channel from the other end thereof.
