Request InfoESCATEC Switzerland AGHEERBRUGG, Switzerland, Nov. 18, 2015 — Meant for high-brightness LEDs, the next-generation total internal reflection (TIR) lens from the Escatec Group is a 20th of the size of current TIR lenses. Mounted directly onto a bare LED and secured in place with clear optical glue, the lens features no air gap for optimal optical coupling, ensuring light transfer from the LED to the TIR lens with minimal sideways losses for optical efficiency up to 95 percent. The lens can be made from polymethyl methacrylate (PMMA), silicone or glass.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/16/2024Eye-Tracking Metalens CameraThe metaEye™ from NIL Technology is an ultracompact metalens-based camera with applications for eye-tracking, smart locks, biometrics, simultaneous localization and mapping, and ubiquitous...Photonics Spectra November 2023 IssueLEDiL Optics KitThe New Energy LEDiL Optics Kit (NELOK) from NewEnergy consists of a single LED mounted on a printed circuit board and attached to a heatsink along with 15 lenses, three each from five lens families....Photonics.com 6/2/2023Low-light LensThe Model 313 fixed-focus lens from Resolve Optics Ltd. has an aperture of f/1.4 to enable maximum light gathered and transmitted to a sensor.
