Patent ID: 8578646

Claim:
A “moving red dot” firearm sighting device, comprising a single, fixed, quasi punctual light source, a collimator comprising a convergent lens having a focal point, the light source located at the focal point, a semi-transparent beamsplitter, and a mirror located between the collimator and the beamsplitter, said mirror being rotatable about an inclination adjusting axis, wherein the light source and collimator project a collimated light beam along an optical axis which is projected onto the beamsplitter via the rotatable mirror so as to produce a red dot or reticle which is visible to a shooter due to the reflection of the collimated light beam on the beamsplitter, and wherein an inclination angle of the optical axis of the light beam projected onto the beamsplitter is adjustable by rotation of the mirror about the inclination adjusting axis.
