Request InfoFocus Mechanism with Non-Rotating OpticsEdmund Optics Inc.BARRINGTON, N.J., Nov. 17 -- Edmund Optic's family of beam expanders offer high performance optical designs packaged in a precise optomechanical platform. Two full rotations of the focus knurl provide smooth movement for the optics in order to vary the output from collimated to the minimum focus distance of 1.2 m. The focusing mechanism keeps optics from rotating, which helps maintain bore sight accuracy and a minimally aberrated focused beam, while the focus lock secures its position. The beam expanders are easily secured to both metric and English threaded mounts. Four tapped holes (two M6...See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2023 IssueNear-Eye Display Test SolutionThe diversity of XR devices and their measurement requirements continue to grow — new display types, fields of view, resolutions, focal distances, form factors, and unique combinations of these...Photonics Spectra September 2023 IssueModular Beam ExpanderOptical Surfaces’ pre-aligned large diameter beam expander modules enable complex 5-degrees of freedom set-up in a matter of minutes.
