The device has a fixed light source (4) producing a collimated light beam projected onto a reflecting blade (17) e.g. semi-transparent beamsplitter plate, so as to obtain a red dot or reticle. The light source has a collimator with a convergent lens and a quasi punctual luminous source placed in a focal point (8) of the lens of the collimator. An adjusting device is arranged to enable adjustment of an inclination angle of a rotating mirror (9) in relation to the light beam, where the adjusting device is provided with several scales for different ammunition. |
