StellarNet’s high performance RED-Wave-NIRX-SR Spectrometers cover the NIR wavelength range from 900-2200μm in one unit. The spectrometers are exceptionally robust with no moving parts and are packaged in small rugged metal enclosure (2.75” x 4” x 6”) for portable, processes, and lab applications. The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels (1024 optional) 25μm by 250μm tall to provide best signal performance. The detector has an integrated two-stage thermo electric cooler (TEC) maintained at –20 °C, stabilized within +/-0.1°C. The RED-Wave-NIRX-SR-InGaAs spectrometers use single strand SMA 905 fiber optic input.
Ruggedized – The detachable spectrograph assembly and control electronics are protected inside a rugged metal enclosure, suitable for portable, process, lab, and field applications.
Onboard Memory with pre-set calibrations, spectrometer settings, and snap shot memory to provide an instantaneous spectral image from the InGaAs array.
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. ContactUs@StellarNet.us for more info.
NIR Applications include chemical absorption, moisture analysis, transmission of filter and optical components, and high power radiometric measurements such as laser characterization. Contact a StellarNet application sales engineer for any other application inquiries.

RED-Wave-NIRX-SR Sample Spectra
RED-Wave-NIRX-SR InGaAs 512 pixels spectrum showing spectral characteristics of Tylenol, Excedrin PM, and Ibuprofen tablets. Often NIR spectroscopy is used as a non-contact method to distinguish between coatings.

Fats and oils constitute the main source of energy and essential fatty acids in the human diet. Additionally, fats and oils function as lubricants in equipment and carriers of fat-soluble vitamins and pigments. Exploring the NIR past 1700nm allows us to identify some of the more important spectral feastures of fats and oils. Above is a spectrum of the StellarNet low dark Noise NIRX (900-2300nm) showing important spectral features past 1700nm such as Fatty Acids absorbance bands at 1750nm and oil saturation absorbance at 2100nm.
Coffee in addition to many other agricultural products shows very important spectral characteristics past 1700nm. Commercial coffee is mainly made up of two main blends, Arabica and Robusta. Main distinguishing absorptions can be found from water content (1466nm and 1962nm) and lipids. NIR spectroscopy can be used for classification as well as blending. Also, caffeine and dry matter content can be determined. For food quality control and identification of adulterants it is very important to test all parts of the NIR region.
Dual System Configurations
All NIRX-SR units can be coupled with StellarNet’s BLACK-Comet or UVN-SR units to cover the entire 200-2300nm range. Coupling the units can provide you with quick analysis of color in the visible spectrum and additionally compound analysis though compound fingerprint identification in the near infrared spectrum.
