The BLACK-Comet UV-VIS spectrometers utilise a 40mm diameter concave grating with aberration correction to provide superb spectral imaging. This significantly improves spectral shapes by reducing comma and astigmatism found in plane grating spectrograph designs. The spectrograph architecture does not utilise mirrors, and therefore provides the lowest possible stray light in the UV with additional assistance from the holographic line grating. The concave grating produces a flat field on the CCD detector creating uniform resolution over the entire range. The instruments are exceptionally robust with no moving parts, and are packaged in small rugged metal enclosures (70 × 101 × 152mm) for portable spectroradiometry and lab or process spectroscopy measurements..
