Request InfoTeledyne Acton OpticsACTON, Mass., July 31, 2015 — Acton Optics & Coatings, part of Princeton Instruments Inc., has announced the 193-nm XL high-reflectance coating for low-fluence, high-repetition-rate excimer laser applications. The multilayer dielectric coating features a ≥96 percent (45° angle of incidence) to ≥97 percent reflectance (normal incidence) at 193 nm. It combines a hybrid structure with balanced stress, optimized for excimer laser repetition rates of 4 to 5 kHz. The possibility of catastrophic damage due to microdefects and thermal stress fractures is reduced, while dehydration effects from...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 10/3/2023Optical Design SoftwareThe Thinoxide software suite from Thinoxide Software Ltd. is a web-based optical design software that is free to use, providing a graphical implementation of the thin-film transfer-matrix method for...Photonics.com 8/31/2022Broadband and Wide-angle Laser Line MirrorsBroadband and Wide-angle Laser Line Mirrors from Knight Optical Ltd. feature an Ion Beam Sputtered (IBS) coating to meet the demanding requirements sought by laser system manufacturers. ...BioPhotonics Jan/Feb 2023 IssueZinc Selenide OpticsHigh-quality zinc selenide (ZnSe) lenses, output couplers, and mirrors from Laser Research Optics are optimized at 1.06 μm for medical laser OEMs. The devices are manufactured to...Photonics Spectra January 2023 IssueSteering MirrorsPiezo and voice-coil steering mirrors from Physik Instrumente LP are designed for free space optical communications.
