Viewing optic with an integrated display system
The disclosure relates to a viewing optic. In one embodiment, the disclosure relates to a viewing optic having an integrated display system. In one embodiment, the disclosure relates to a viewing optic having an integrated display system for generating images that are projected into the first focal plane of an optical system.
1. A viewing optic comprising:
a body having an objective lens system at one end that focuses a target image from an outward scene,
an ocular lens system at the other end of the body and a movable erector tube with an erector lens system located between the objective and ocular systems, the erector lens system, the objective lens system and the ocular lens system forming an optical system having a first focal plane with a first reticle at the first focal plane;
a beam combiner located between the first focal plane and the objective lens system; and
an active display configured for generating an image and a collector lens system configured to collect light from the active display, wherein the collector lens system is a 5 lens system having an inner lens cell with 2 lenses and an outer lens cell with 3 lenses, and a reflective material configured to direct the generated image from the active display to the beam combiner where the image from the active display and the target image from the objective lens system are combined into the first focal plane and viewed simultaneously.
2. The viewing optic of claim 1 , wherein the image from the active display is not tied to the movement of the erector tube.
3. The viewing optic of claim 2 , wherein the image is a digital reticle.
4. The viewing optic of claim 1 , wherein the beam combiner is located from 5 to 25 mm from the objective lens system.
5. The viewing optic of claim 1 further comprising a focusing cell located between the beam combiner and the objective lens system.
6. The viewing optic of claim 5 further comprising a rod connecting the focusing cell to a parallax adjustment knob.
7. The viewing optic of claim 6 wherein the rod is from 25 to 33 mm in length.
8. The viewing optic of claim 1 , wherein the active display is selected from the group consisting of: a transmissive active matrix LCD display (AMLCD), an organic light-emitting diode (OLED) display, a Light-Emitting Diode (LED) display, an e-ink display, a plasma display, a segment display, an electroluminescent display, a surface-conduction electron-emitter display, and a quantum dot display.
9. The viewing optic of claim 1 , wherein the image generated by the active display is selected from the group consisting of: text, alpha-numeric, graphics, symbols, video imagery, icons, active target reticles, range measurements, wind information, GPS and compass information, firearm inclination information, target finding, recognition and identification (ID) information, external sensor information, temperature, pressure, humidity, real time ballistic solutions, and next round ballistic correction through in-flight tracer round detection and tracking.
10. The viewing optic of claim 1 , wherein the reflective material is a mirror.
11. The viewing optic of claim 10 , wherein the mirror is angled from about 40° to about 50° relative to the emitted light of the active display.
12. The viewing optic of claim 1 , further comprising a controller coupled to the active display, the controller configured to selectively power one or more display elements to generate the image.
13. The viewing optic of claim 1 , further comprising a laser range finder coupled to a top portion of the body.
14. A viewing optic comprising: (a) a main tube; (b) an objective system coupled to a first end of the main tube that focuses a target image from an outward scene; (c) an ocular system coupled to the second end of the main tube, the main tube, objective system and ocular system being configured to define at least a first focal plane, with a first reticle at the first focal plane; (d) a beam combiner positioned between the objective assembly and the first focal plane; and (e) an active display for generating an image and a collector lens system configured to collect light from the active display, wherein the collector lens system is a 5 lens system having an inner lens cell with 2 lenses and an outer lens cell with 3 lenses, wherein the generated image and the target image are combined into the first focal plane.
15. The viewing optic of claim 14 , further comprising a reflective material for directing the image to the beam combiner.
16. The viewing optic of claim 14 , wherein the beam combiner is located from 5 to 25 mm from the objective system.
17. The viewing optic of claim 14 , wherein the generated image from the active display is unaffected by a turret adjustment.
