Request InfoMcPHERSONModel 248/310G grazing incidence spectrometers operate from <1 to 310 nm with a variety of gratings and are optimal for use at <100 nm. The instruments, designed by McPherson Inc., have working ranges that overlap those of crystal and normal-incidence devices. They have a 1-m focal length with variable angles of incidence, built-in filter holders and various single- and multichannel detection schemes. The spectrometers are available in high-vacuum and ultrahigh-vacuum versions and are equipped with intensifiers for surveying broad spectral regions for laser or plasma diagnostic...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...BioPhotonics Mar/Apr 2024 IssueBragg Grating Notch FiltersThe WSF series from TeraXion comprises all-fiber band-stop (notch) filters that are used to selectively attenuate or block a wavelength or a range of wavelengths while allowing others to pass...Photonics 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.
