Request InfoThorlabs Inc.Volume 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. VPH gratings consist of a gelatin film with periodic index modulations that is sealed between two AR-coated glass substrates, providing low scatter of stray light between diffraction order peaks and minimal ghosting for use in spectroscopy and optical coherent technology applications. Customized round or square optics can be achieved with dimensions as small as 10 mm and as large as 60 mm. ...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2023 IssueOptical Reference CavitiesThe XM-ORC series of optical reference cavities with crystalline mirrors from Menlo Systems GmbH and Thorlabs Inc. is stable at the zero-crossing of the thermal expansion coefficient.

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 HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookNano-Optics Technology: Optical Alchemy: Transforming ordinary materials into extraordinary optics holds the key to progress.Optics today needs alchemy, and the forces that motivate microchip technology are a key reason why.
