Request InfoTeledyne Princeton InstrumentsPrinceton Instruments/Acton has released the SpectraPro HRE spectrograph, which offers high spectral resolution combined with simultaneous wavelength coverage. Suitable for use with the company’s CCD and intensified CCD camera systems, the instrument uses the echelle grating principle and can sample wavelengths ranging from 190 to 1050 nm continuously, with no moving parts. It can be configured down to 150 nm when required. Controlled by WinSpec software, it features interchangeable wavelength-dispersive elements, enabling users to select the appropriate resolution and wavelength for an...See full productRelated content from Photonics MediaARTICLESPhotonics.com 4/26/2022Hyperspectral Method Adds Speed, Accuracy to Wafer InspectionA high-throughput metrology technique for semiconductor manufacturing, developed by Samsung Electronics, combines spectroscopy and imaging to measure in-cell uniformity (ICU) and in-wafer uniformity...WEBINARSPhotonics.com 1/21/2021Rapid Reaction Monitoring via QCL-Based Mid-IR Dual-Comb SpectroscopyUnderstanding the mechanism of a chemical reaction is an important step away from trial-and-error-based reaction optimization.
