StellarNet has announced the NIRX-SR series of spectrometers for the 0.9-2.3μm wavelength range with a 512 element InGaAs Photo Diode Array and high speed USB-2.0 interface. The extended range detector operates using a 2-stage TE cooler and includes optics to deliver high spectral efficiency. A 1024 element detector array is available to double the resolution from <16nm on the 512 model to <8 nm for special spectroscopy applications. The spectrograph optics have no moving parts for shock-proof durability in a truly portable environment.

Optional fiber optic accessories are available for chemical analysis of liquids such as the SL1-CUV halogen light source with integrated 1cm cuvette holder as shown in photo. Also available are dip probes with replaceable tips of various path lengths (eg: 0.5cm, 1cm, 2cm, etc.) Longer path lengths allow for lower concentrations measurement. For chemical analysis of solids the RFX1 reflectance fixture with integrated halogen light source allows placement of samples on top in Petri dish or on glass plate. For optical spectroscopy measurements the TXF3 transmission fixture allows adjustment for sample placement between 2 collimating lens attached via fiber optic cables to the NIR spectrometer and SL1 halogen light source.

The SpectraWiz® software suite is included free-of-charge to immediately enable a variety of spectroscopy measurements. This includes "customizable" programs for LabVIEW and direct operation from MS Excel via Visual Basic Automation.

StellarNet builds ruggedized miniature fiber optic spectrometers for a complete spectrum of Lab and Field measurements. Using our fiber optic sampling accessories and SpectraWiz® software you can have accurate and reliable instrumentation for a variety of applications at a surprisingly low cost.
