Request InfoVescent Photonics LLCGOLDEN, Colo., April 29, 2015 — A nonmechanical beam-steering device from Vescent Photonics Inc. operates at the crossroads of waveguide and liquid crystal (LC) technologies. The SEEOR (Scannable Electro-Evanescent Optical Refractor) can continuously steer a near-infrared laser beam over a 30° × 5° field of view with a full frame rate <50 ms. The beam is refracted by prismatic structures in an LC-based cladding to the waveguide. The electro-optic coefficient of the LC (up to 100,000 times that of LiNbO3) allows voltage tuning of the index of the prisms, and hence the refraction angle of the...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2023 IssueOffset Phase Lock ServoThe SLICE-OPL Offset Phase Lock Servo from Vescent Photonics LLC is designed to precisely control and quickly adjust the frequency detuning between a master and a follower laser.
