Request InfoEdmund Optics Inc.Modular fixed-power beam expanders from Edmund Optics offer high-performance optical designs in an optomechanical platform. Two full rotations of the focus knurl provide smooth movement for the optics to vary the output from collimated to the minimum focus distance of 1.2 m. The precise focusing mechanism keeps the optics from rotating and helps maintain boresight accuracy and a minimally aberrated focused beam. The expanders can be secured to both metric and English threaded mounts. Interchangeable 3×, 5×, 10×, 15× and 20× rear accessory attachments change the beam expander’s magnification.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/31/2022Antireflection Laser WindowsTECHSPEC® Dual-Band Antireflection (AR) Laser Windows from Edmund Optics Inc. feature <0.25% reflection at 532 nm and <0.1% reflection at 1064 nm for high laser throughput. ...Photonics Spectra November 2022 IssueLaser Line MirrorsTECHSPEC® Dual Band Laser Line Mirrors from Edmund Optics Inc. offer 99% reflectivity at both IR and visible wavelengths.
