Optical mini spectrometer DWARF-Star series

NIRprocessrobust

Spectral resolution down to 1nm for certain models Miniature size 5x3x2″ with rugged, compact design Integrated thermo electric cooler set to operate at -15 deg C Complete Software Development and Integrated Chemometrics options For NIR portable and OEM applications The StellarNet DWARF-Star NIR spectrometers are fiber optically coupled instruments with a wide selection of models for measurements in the 900-1700nm wavelength range achieving resolving resolutions down to 1.25nm. High performance InGaAs detectors from Sensors Unlimited are installed in each DWARF-Star with options for 512 or 1024 linear pixels. Each pixel is 25μm by 500μm tall to provide maximum sensitivity. The detector has an integrated thermo electric cooler (TEC) maintained at –15 degrees, stabilized within +/-0.1 °C (optional 2-stage cooling is available). Various models provide a choice of grating 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 4000:1! Includes 10x electronic gain mode. 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 can be daisy chained together and are able to run simultaneously.
