Concave-grating spectrometers
The BLACK-Comet spectrometers from StellarNet use a holographic aberration-corrected concave grating for UV–vis and UVN measurements. According to the company, the instruments' spectrograph contains no mirrors to minimize stray light while projecting a flat field to the detector array. The SR model includes a dual blaze grating that reportedly provides high efficiency for UV and NIR wavelengths. The spectrometers are housed in extruded aluminum enclosures, and SpectraWiz software and OEM drivers and customizable programs for LabView and Excel-VBA are included. StellarNet, Inc., Tampa, FL;
