Request InfoG&HGooch & Housego plc has introduced the M110-1×-GH1 and -GH2 all-purpose acousto-optic modulators with broadband antireflection coatings for amplitude modulation of a variety of low-power gas and diode lasers. Available for use in the visible (450 to 650 nm) and the VIS/NIR (650 to 850 nm) regions, their interaction material is lead molybdate. Transmission is >95%, rise and fall time is 180 ns/mm, typical diffracted beam ellipticity is <5%, and typical diffraction efficiency is >85%. The GH1 models have a 1-mm active aperture, and the GH2, 2 mm.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...Promoted Content June 2022 IssueAR Conformal CoatingsDeposition Sciences’ exclusive IsoDyn™ low pressure chemical vapor deposition (LPCVD) technology is a high-temperature process that deposits extremely conformal coatings on a wide variety...Photonics Showcase March 2024 IssueHigh-Quality Optical CoatingsEvaporated Coatings Inc. is a professional and experienced resource for your Thin-Film Optical Coating requirements.
