OPTICAL ELEMENTS, DEVICES, AND SYSTEMS COMPRISING HALIDE MATERIAL COMPOSITIONS SOLIDIFIED FROM MELTS
Publication number: 20250236552Abstract: Embodiments of the present disclosure are directed to infrared optical lightguides or fibers formed with molten halide material (e.g., silver halide), which can provide low loss broadband transmission of wavelengths from approximately 0.5 microns to approximately 25 microns, and methods for forming such lightguides or other optical devices based on solidifying halide melts. In some embodiments, surfaces of a retaining element may be passivated (e.g., using a silver ion exchange process) before the molten halide material is deposited into the retaining element. In some embodiments, the molten halide material may be solidified in a microgravity environment.Type: ApplicationFiled: November 25, 2024Publication date: July 24, 2025Applicant: DSTAR Communications, Inc.Inventors: Dmitry Starodubov, Viktor Dubrovin -
Patent number: 12345505Abstract: The present disclosure describes a single aperture laser range finder (SALRF). In an implementation, the single aperture laser range finder includes a beam extender including an aperture and an input aperture lens. A matching lens collimates light emitted from an emitter element associated with a single aperture optical circulator and received by the beam extender, respectively. A single aperture optical circulator has an emitter channel associated with the emitter element and a detector channel associated with a detector element. The emitter channel and the detector channel merge together at an input/output aperture.
