Request InfoStellarNet Inc.StellarNet Inc. has released a line of SR (superrange) spectrometers that cover the 200- to 1100-nm-wavelength range. An aberration-corrected concave grating with dual-blaze technology provides high imaging quality and spectral efficiency. The spectrograph contains no mirrors to minimize stray light, while the flat-field grating delivers a uniform focus on the detector for less than 2-nm resolution. The device connects directly to a PC’s USB-2 port and includes SpectraWiz software for spectroscopy, radiometry and LED measurements.See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2023 IssueOrder Sorting FiltersWhen the spectrum of a spectrometer covers more than one octave, the multiple orders from the grating make interpretation of the detected spectrum difficult.
