StellarNet spectrometer offers aberration correction

April 9, 2011
The BLACK-Comet-HR 16 bit concave-grating spectrometer is available for UV and visible measurements, and achieves resolution of 0.4 nm.

The BLACK-Comet-HR 16 bit concave-grating spectrometer is available for UV and visible measurements, and achieves resolution of 0.4 nm. A holographic concave grating with aberration correction improves spectral imaging by reducing coma and astigmatism. The flat-field spectrograph architecture does not use mirrors, reducing stray light effects while providing uniform resolution across the entire spectral range.

PRESS RELEASE

StellarNet Releases New High Resolution Concave Grating Spectrometer

BLACK-Comet-HR Concave Grating Spectrometer Series

StellarNet, inventors of the first miniature, concave grating spectrometers, introduces the newest member to its BLACK-Comet line-up: the BLACK-Comet-HR. Designed for high resolution applications, the new BLACK-Comet-HR spectrometer is available for measurements in two ranges - UV (200-600nm) and Visible (380-750nm), and achieves resolving resolutions of 0.4nm. This 16-bit concave grating spectrometer is USB-2 powered, shock-proof and vibration tolerant with no moving parts, includes the powerful SpectraWiz® spectrometer software and development kit, and is available at an extremely low price of $2,750.

The BLACK-Comet spectrometers utilize a holographic concave grating with aberration correction to provide superb spectral imaging. This significantly improves spectral shapes by reducing comma and astigmatism found in all other plane grating miniature spectrometer designs. The flat field spectrograph architecture does not utilize mirrors and therefore drastically reduces stray light effects while providing uniform resolution across the entire spectral range. With over 20 years of tested quality, StellarNet’s patented optical design with permanent alignment requires no calibration adjustments to provide unbeatable thermal stability without wavelength drift. Additional popular concave grating models cover 190-850nm or 200-1100nm ranges in one instrument. Now research grade performance is available at a fraction of the price!
