Request InfoAltechnaVILNIUS, Lithuania, March 5, 2014 — Altechna’s gradient index (GRIN) lenses are suitable for applications in beam collimation or focusing, and laser-to-fiber, fiber-to-fiber and fiber-to-detector coupling. Lenses with 0.25 pitch have a 0-mm working distance and are suited for beam collimation of optical fibers or laser diodes. The 0.23-pitch lenses have a small working distance and are used for focusing. Lenses are available with one 8° wedged face and broadband antireflection coating to reduce back reflections.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2024 IssueF-Theta Objective LensThe JENar™ Silverline™ 340-355-332-S from Jenoptik is an F-Theta objective lens for laser material processing that is specially designed to meet the requirements of solar cell production....Vision Spectra Spring 2023 IssueColor CameraThe EoSens 21CCX12-FM color camera from Mikrotron GmbH combines 5120 × 4096-pixel resolution with the CoaXPress 2.0 interface to deliver 230 fps at full resolution.
