DWARF-Star Miniature NIR Spectrometer - 1

www.StellarNet-Inc.com Analytical Instrumentation Surf the New Wave in Portable Fiber Optic Spectrometry NIR Spectrometers for Portable & OEM Applications StellarNet’s newest NIR spectrometer, the DWARF-Star, is small, robust, and equipped with high performance InGaAs detector array for the 900-1700nm wavelength range and achieves resolving resolutions to 1.25nm. The DWARF-Star features no moving parts and is packaged in a small rugged metal enclosure (5”x3”x2”) for portable, process, and OEM applications. Advancements in electronic and optical design have allowed for size reduction never before achieved in a NIR spectrometer. The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels (1024 optional) 25µ m by 500µ m tall to provide maximum sensitivity. The detector has an integrated thermo electric cooler (TEC) maintained at –10 °C, stabilized within +/-0.1 °C. The NIR spectrometers accept a single strand SMA-905 terminated, low OH, fiber optic cable as input. Several models provide a variety of operational ranges and resolutions suitable for both spectroscopy and optical spectrum analysis. Each DWARF-Star includes free SpectraWiz® Software and a developer’s toolbox of source codes, customizable demo programs, and full spectroscopy applications in LabVIEW, Visual Basic, Delphi Pascal, and MS Visual C. High speed spectral data acquisition with advanced features, such as time series analysis and episodic data capture with rapid sample logging are standard features. Post processing techniques such as baseline correction, data smoothing, and spectral derivatives are included. Additionally, add-on chemometrics packages are available for complete multivariate calibration, analysis, and runtime with the DWARF-Star.
