Abstract

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.

First claim

What is claimed is:

1. A viewing optic comprising: a body, an objective assembly coupled to a first end of the body configured to focus a target image from an outward scene to a first focal plane, an ocular assembly coupled to the second end of the body; an erector lens system, a beam combiner located between the objective assembly and the first focal plane, a magnification ring coupled to an external portion of the body; an active display configured to generate an image, a lens system configured to collect light from the active display and having an inner lens cell and an outer lens cell, the inner lens cell having an asphere and the outer lens cell having a doublet lens and a singlet lens, with the singlet lens being furthest from the active display, wherein the generated image and target image of the outward scene are combined in the first focal plane and a magnification tracking system to scale the generated image from the active display upon adjustment of the magnification ring.

2. The viewing optic of claim 1 , wherein the beam combiner is located approximately beneath an elevation knob of the viewing optic.

3. The viewing optic of claim 1 , wherein the beam combiner is located closer to the objective assembly as compared to the ocular assembly of the viewing optic.

4. The viewing optic of claim 1 , further comprising a reflective material configured to direct the generated image to the beam combiner.

5. The viewing optic of claim 4 , wherein the reflective material is a mirror angled from about 40° to about 50° relative to emitted light from the active display.

6. The viewing optic of claim 5 , wherein the mirror is angled at about 45° relative to emitted light from the active display.

7. The viewing optic of claim 1 , wherein the image generated by the active display is selected from the group consisting of: active target reticles, firearm inclination information, target finding, recognition and identification (ID) information, real time ballistic solutions, and next round ballistic correction through in-flight tracer round detection and tracking.

8. The viewing optic of claim 1 , wherein the image generated by the active display is a real time ballistic solution.

9. The viewing optic of claim 1 , wherein the image generated by the active display is a ballistic correction through in-flight tracer round detection and tracking.

10. A system comprising the viewing optic of claim 1 and a firearm.

11. A viewing optic comprising:
an optical system having an objective lens system that focuses a target image from an outward scene to a first focal plane, an erector lens system that inverts the target image, a beam combiner located between the objective lens system and the first focal plane; and a magnification ring;
an active display configured to generate an image and a collector lens system configured to collect light from the active display and having an inner lens cell and an outer lens cell, the inner lens cell having an asphere and the outer lens cell having a doublet lens and a singlet lens, with the singlet lens being furthest from the active display, and a reflective material configured to direct the generated image from the active display to the beam combiner, wherein the generated image and the target image from the objective lens system are combined into the first focal plane; and
a magnification tracking system to scale the generated image from the active display upon adjustment of the magnification ring.

12. The viewing optic of claim 11 , wherein the collector lens system is a five lens system.

13. The viewing optic of claim 11 , wherein the asphere is within 2 mm of the active display.

14. The viewing optic of claim 11 , 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, a e-ink display, a plasma display, a segment display, an electroluminescent display, a surface-conduction electron-emitter display, and a quantum dot display.

15. The viewing optic of claim 11 , 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.

16. The viewing optic of claim 11 , wherein the beam combiner is located from 5 to 25 mm from the objective lens system.

17. A viewing optic comprising:
an optical system having an objective lens system that focuses a target image from an outward scene to a first focal plane, an erector lens system that inverts the target image, a beam combiner located between the objective lens system and the erector lens system;
and a magnification ring;
an active display configured to generate an image; a collector lens system configured to collect light from the active display and a reflective material configured to direct the generated image from the active display to the beam combiner, wherein the generated image and the target image from the objective lens system are combined into the first focal plane; and
a magnification tracking system to scale the generated image from the active display upon adjustment of the magnification ring.

18. The viewing optic of claim 17 , wherein the collector lens system is located between the active display and the reflective material.

19. The viewing optic of claim 18 , 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.
