Request InfoEdmund Optics Inc.BARRINGTON, N.J., Dec. 15, 2017 — TECHSPEC Divergence Adjustable Fixed YAG Beam Expanders from Edmund Optics Inc. are compact beam expanders designed for demanding laser applications including laser materials processing, medical treatments and research. The expanders are optimized for common Nd:YAG wavelengths including 1064, 532, 355 and 266 nm for high-performance transmitted wavefront. The beam expanders can be adjusted to increase or decrease the divergence angle for precise divergence adjustment to compensate for input beam divergence. The devices are ideal for both single-unit purchases or volume integration.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.
