Request InfoMcPHERSONMcPherson Inc.’s 248/130 grazing incidence wavelength dispersive optical spectrometer enables rapid analysis of spectral light in the ~1- to 300-nm wavelength region (4 to ~1200 eV). It is useful for spectroscopy in the vacuum-UV and also the extreme- and soft-x-ray wavelength regions. Using direct-detection CCDs, gated image intensifiers or fast channel electron multipliers for detection, it provides a wide working range and flexibility in spectral acquisition. It is completely assembled, vacuum leak-checked and calibrated with respect to wavelength. It can include adapters, differential...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/2/2024Flow Cell and Reflection StrobeThe ATR Flow Cell and near infrared diffuse reflection probe (shown) from tec5USA Inc. are 3-A certified and can be used for applications including spectroscopic analysis for food, feed, and...Photonics Spectra March 2023 IssueOptical Inspection SystemThe Photon Optical Inspection System from LMI Technologies Inc. provides fast, high-precision scanning of manufactured materials.
