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.
NIR Applications
include chemical absorption, moisture analysis, transmission of
filter and optical components, and high power radiometric measurements
such as laser characterization.

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.
