TAMPA, Fla., Feb. 23, 2007 -- StellarNet Inc., a maker of miniature fiber-optic spectrometers and accessories for spectroscopic and optical measurements, has announced the NIRX-SR, a "super range" series of spectrometers for the 0.9- to 2.3-µm wavelength range with a 512-element InGaAs photodiode array and high-speed USB-2.0 interface.

StellarNetNIRX-SR.jpgThe extended range detector operates using a two-stage thermoelectric cooler and includes optics to deliver high spectral efficiency. A 1024-element detector array is available to double the resolution from <16 nm 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, the company said.

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

The included SpectraWiz software suite enables a variety of spectroscopy measurements, including "customizable" programs for LabVIEW and direct operation from MS Excel via Visual Basic Automation.

GLOSSARY
detector
1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
spectrometer
A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
