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 Showcase July 2023 IssueDual-Band Infrared AR CoatingsInfrared imaging systems require simultaneous performance MWIR (midwave, typically 3 to 5 μm) and LWIR (longwave, typically 8 to 12 or 7.5 to 13.5 μm) spectral bands.
