Request InfoMcPHERSONThe Model 207V high-vacuum spectrometer from McPherson Inc. works over a broad spectral range for contaminant-free purge and vacuum applications. The Model 207V is a 670-mm focal length, optically fast f/4.7 monochromator with a vacuum tight housing. Stigmatic performance with off-axis parabolic optics is available for the 207V as well. With stainless steel housing capable of 10E-6 torr vacuum, the instrument works unfettered over a very wide wavelength range. Depending on the installed grating, the system can go from 110 nm to 15 μm. The 50-mm wide focal plane is great for...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/19/2024Combination Transceiver ModuleThe XGS-PON & GPON combo OLT SFP+ BiDi optical transceiver module from Integra Optics integrates the functionality of XG(S) PON OLT and GPON OLT optical modules, facilitating network rate...Photonics.com 3/28/202416-Wavelength Light SourceThe SuperNova™ from Ayar Labs is a 16-wavelength light source meant for AI and optical I/O applications.
