BLACK-Comet-SR Spectrometer

Research 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.

• 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.

• Thermal 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

Dual blaze super range models: provide wide wavelength ranges. Choose from the tables of standard models with various slit options for your choice of slit resolution. New and improved electronics with a high speed 16-bit digitizer allows for fast data acquisition and a signal to noise of 1000:1!

Ruggedized:  The detachable spectrograph assembly and control electronics are protected inside a rugged metal enclosure, suitable for portable, process, lab, and field applications.

Multi-unit connection (up to 8): can be daisy chained together and are able to run simultaneously.

USB Powered: BLACK-Comet-SR UV-VIS-NIR spectrometers can be powered directly from your PC’s USB-2 port. A single strand fiber optic cable or probe assembly delivers input via standard SMA 905 fiber optic connector with a choice of cable lengths.

Onboard Memory: with pre-set calibrations and spectrometer settings and snap shot memory to provide instantaneous spectral image from the highly sensitive CCD with 2048.

High Speed Electronic Interface: can be attached directly to a computers USB port for high speed data transfer. Options for Wifi/ethernet communication available as well as other interfaces.
