INTEGRATED OPTICAL SIGHTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/060975
Kind Code:
A8
Abstract:
A direct view optical sighting system. In certain examples the system includes an eyepiece, an objective that directs scene light to the eyepiece, a laser rangefinder, and a laser rangefinder coupling prism that directs a laser transmit beam from the laser rangefinder to the objective and a laser return beam from the objective to the laser rangefinder. Examples of the system further include a display assembly including a reticle prism and a display coupling prism, the reticle prism being positioned along the optical path between the laser rangefinder coupling prism and the display coupling prism and having a hard reticle formed on a surface thereof. The objective can be configured to produce a first focal plane of the optical sighting system coincident with the first surface of the reticle prism. The display coupling prism is configured to direct display light toward the eyepiece. Examples of the system also include a zoom relay positioned between the display coupling prism and the eyepiece and configured to adjust a magnification of the optical sighting system.
