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.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookIndustrial Lasers: An Introduction to Process Qualification: The step from successfully demonstrating a new laser process on a limited number of samples under laboratory conditions, to scaling that process up for high-volume industrial use is a big one. In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1.
