DWARF-Star Miniature NIR Spectrometer Features

NIR Measurements in the 900-1700nm range 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 DWARF-Star NIR Spectrometer Overview 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. USB powered directly from your PC’s USB port. DWARF-Star spectrometers come with integrated TE coolers which can be activated with 5VDC power adapter included with each system; however, many applications can be ran without cooling. Onboard Memory with pre-set calibrations and spectrometer settings and snap shot memory to provide instantaneous spectral image. High Speed Electronic Interface can be attached directly to a computers USB port for data transfer or zAP2 upgrade for wifi control. Many Options & Upgrades – The DWARF-Star spectrometer platform supports a variety of options and upgrades such as TTL triggering options, zAP 1 & 2 electronics upgrades for increased dynamic range, burst acquisition, and onboard CPU with Wifi communication. See more information below under DWARF-Star options. ContactUs@StellarNet.us for more info. StellarNet also offers light sources, probes, and sampling accessories to facilitate virtually any NIR application. The miniature DWARF-Star NIR spectrometer is ideal for process analytical technology for industries such as food and drug, chemical, oil and gas, and plastics. The DWARF-Star’s miniature size, low cost, and rugged design also make it ideal for the field, enabling on-site product analysis and quality control never before attainable.
