03 Mar 2008 StellarNet's SUPER RANGE, concave grating spectrometers cover the range from 220-1100nm. StellarNet SUPER RANGE spectrometers cover the range from 220-1100nm. An aberration corrected concave grating provides superb imaging and top spectral efficiency with unique dual-blaze technology.The spectrograph contains no mirrors to minimize stray light while the flat field grating delivers a uniform focus on the detector for <2nm resolution. The spectrometer connects directly to a PC's USB-2 port and includes SpectraWiz software for spectroscopy, radiometry and LED measurements. |
