Fiber-optic spectrometer / laboratory - 200 - 1 100 nm | BLACK-Comet-SR
StellarNet has developed a "Super Range" concave grating spectrometer for UV-VIS-NIR range from 200-1080nm or 220-1100nm. The concave holographic grating is aberration corrected and has no mirrors to minimize stray light with superb imaging projecting a flat field on the detector. Additionally, the grating has a dual blaze to provide high efficiency in both the UV and NIR wavelengths. The optics can be fitted with choice of detectors with 2k/3k element CCD or PDAs. StellarNets' miniature fiber optic spectrometers with concave gratings deliver high performance. The instruments are exceptionally robust with no moving parts, and are packaged in small rugged metal enclosures (2.75 x4 x6 inch) for portable spectroradiometry and lab or process spectroscopy measurements. The Dual Blazed Concave Grating significantly improves spectral shapes by reducing comma and astigmatism found in plane grating spectrograph designs. The flat field spectrograph architecture does not utilize mirrors, and therefore provides the lowest possible stray light in the UV with additional assistance from the holographic line gratings.
