Request InfoIRsweepZÜRICH, Feb. 29, 2016 — IRsweep GmbH has announced the IRcell, a multipass cell consisting of one circular mirror for robust, compact and temperature-invariant use. The cell body is a mirror that reflects the optical beam. Long path transmission measurements with minimum optical noise of 0.25 percent rms can be achieved. An initial design offers an optical path of 4 m in a sample volume of 30 ml. The optical path length can be adjusted by changing the incidence angle of the optical beam, accommodating short or long optical paths.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueDual-Comb SpectrometerThe IRis-C spectrometer from IRsweep utilizes dual-comb spectroscopy and quantum cascade laser frequency combs to offer a combination of high speed, high signal to noise ratio per time, as well as...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. ...Photonics Spectra July 2023 IssueMirror MountsWedged back paraboloid mounts from Optical Surfaces Ltd. provide a secure and stable platform for mirror diameters from 50 to 200 mm.
