Research Grade Concave Grating Spectrometer Features Measurements in the 190-850nm or 280-900nm ranges High performance concave grating optics for UV-VIS applications Superb spectral imaging with no mirrors for lowest possible stray light Enhanced UV Sensitivity & Flat-field imaging for uniform resolution No optical adjustments for extreme thermal stability and ruggedness Thermo-electrically Cooled Detector (TEC) upgrade increases S/N by 60% BLACK-Comet-SR (Super Range) for wide range applications 200-1100nm BLACK-Comet-HR (High Resolution) for high resolution applications <0.4nm StellarNet BLACK-Comet concave grating spectrometers deliver high performance for spectroscopy applications in the UV-VIS wavelength ranges covering 190-850nm (model C), or optionally 280-900nm (model CXR) Research Grade Optical Performance – The BLACK-Comet UV-VIS spectrometers utilize a 40mm diameter concave grating with aberration correction to provide the best optical performance of any compact spectrometer on the market. Improved spectral shapes by reducing comma and astigmatism found in plane grating spectrograph designs. Stray light reduction- The spectrograph architecture does not utilize mirrors, and therefore provides the lowest possible stray light, which is especially helpful for UV applications. Enhanced sensitivity- due to the spectrometers ability to reduce light scatter, especially high power UV light, the BLACK-Comet provides two to three times enhanced UV sensitivity as compared to plane grating/Czerny Turner optical configurations. Uniform resolution – The concave grating produces a flat field on the CCD detector creating uniform resolution over the entire spectral range.
