Optical sight comprising an elongate housing (10, 11) defining a light channel, a lens (12) at one end of the light channel, having a partially reflecting surface (13), a light source (14), and a battery for energising the light source. The energised light source emits light towards the reflecting surface to produce a light spot by direct imaging of the light source on the reflecting surface to be superimposed on the target when sighting through the light channel from the other end thereof. According to the invention the light source comprises a resonant cavity light emitting diode. |
