Request InfoMcPHERSONCHELMSFORD, Mass., Jan. 18, 2017 — The VUV-STS vacuum UV spectral test system from McPherson Inc. measures reflectance as a function of angle of incidence. The system measures optical performance at wavelength and can help determine optical constants. It uses special techniques for measuring nonpolarized light and works in the 30- to 160-nm wavelength region. Transmission can be measured as well. The VUV-STS is a 1-m grazing incidence monochromator efficiently coupled to a windowless hollow cathode light source. The sample chamber is mechanically stiff and mounted in widely spaced and well-supported bearings....See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2022 IssueBeam SamplerThe BA32-1KW beam sampler from Gentec Electro-Optics Inc. is designed for kW-level lasers.
