BLACK-Comet Spectrometer

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.
- 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

Various models: provide a choice of wavelength range and slit resolutions. 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 UV-VIS 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.
