Request InfoMcPHERSONCHELMSFORD, Mass., Aug. 2, 2010 — McPherson Inc. has announced that its vacuum-ultraviolet (VUV) spectrometer, the Model 234/302, is now available with improved efficiency over a wide wavelength range. New platinum-coated gratings are suitable for use at windowless wavelengths, shorter than 120 nm (>10eV.) The compact 200-mm-focal-length spectrometer can be supplied with various gratings to spread optimization over the entire 30 to 550-nm wavelength range, an advantage enabled by the optical design. In combination with windowless, sensitive, cooled scientific-grade CCD detectors, adjustable slits and f/4.5, the...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...BioPhotonics May/Jun 2023 IssueBandpass FiltersThe ADVANTECH™ hard coat bandpass filters from Andover Corp. offer steep slopes, high light transmission, durability, and long life for demanding applications.
