BLACK-Comet-SR concave grating spectrometers deliver high
performance spectral analysis in the UV-VIS-NIR wavelength
range covering 200-1080nm (model C-SR) or optionally 220-1100nm
Grade Optical Performance The BLACK-Comet-SR UV-VIS-NIR
spectrometers utilize a Dual Blaze 40mm diameter concave grating
with aberration correction to provide the best optical performance
of any compact spectrometer on the market.
spectral shapes by reducing comma and astigmatism found
in plane grating spectrograph designs.
light reduction - The spectrograph architecture does
not utilize mirrors, and therefore provides the lowest possible
stray light, which is especially helpful for UV applications.
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.
resolution The concave grating produces a flat
field on the CCD detector creating uniform resolution over
the entire spectral range.
Stability - Optical bench architecture without mounting
turrets and optical posts (typically in most USB spectrometers)
decreases thermal expansion and contraction and increases
overall system performance with temperature change
BLACK-Comet Optics- 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
blaze super range models provide wide wavelength ranges.
