Request InfoNewport - Oriel InstrumentsIRVINE, Calif., Feb. 18, 2015 — The 75160NF phase-locked optical chopper system from Oriel Instruments is suited for spectroscopy applications. It combines a chopper controller with an enclosed chopper head and includes four interchangeable chopper wheels. The enclosure prevents scattering and blocks unchopped background light, improving the signal-to-noise ratio. The system integrates with the company’s light sources and monochromators. Optical choppers function by introducing a periodic interruption into the light path in an optical experiment, resulting in an amplitude modulation. This is useful for...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueTunable Laser SystemThe Tunable Laser System from Spectrolight Inc. is an all-in-one tunable light source system that enables precise selection of a broad spectral range from 410 to 1650 nm and easy bandwidth adjustment...Photonics Spectra October 2021 IssueHolographic GratingsVolume phase holographic (VPH) gratings from Thorlabs Inc. are manufactured in-house for high first-order diffraction efficiencies across broad bandwidths and low polarization dependence loss. ...Photonics.com 5/26/2023Raman MicroscopeThe LabRAM Odyssey automated Raman microscope from HORIBA Scientific is a remotely controllable system for micro and macro measurements.

A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookHyperspectral Imaging Spectroscopy: A Look at Real-Life Applications: Spectral imaging has grown from an expensive research-oriented technique to one that is applicable for a wide range of scientific and industrial applications.
