The StellarNet spectrometers are great tools for low cost, routine
analysis of all types of displays and monitors. The
use and popularity of flat panel
displays for televisions,
computer monitors, laptops, automotive
displays, cell phones, and mobile
devices of all kinds requires
accurate, fast, and cost-effective methods for measuring color,
luminance, and various other output parameters.
In R&D applications there is a continuing need for
low cost and easy-to-use measurement systems that can
be applied to all sorts of display sizes,
brightness, and technologies — LCD, plasma, OLED and LED.
In manufacturing, accurate, repeatable, quantitative measurement
methods are needed to replace traditional
human inspection techniques. Also, StellarNet's
line of low cost spectrometers are small, portable, and robust which
allows for a more economical solution to the larger benchtop display
measurement alternatives. Likewise, multiple spectrometers can be
deployed in production facilities, taken into the field, and
transported easily from one location to another increasing the ease
of inspection and quality control.

Standard and Extended Ranges
StellarNet also has extended range
available to measure spectral irradiance over a wide range of
wavelengths. The EPP2000-UVN-SR spectroradiometer with CCD detector array covers a range of 200-1100nm.
BLACK-Comet-SR super range, dual blazed, concave grating spectroradiometer
offers a range of 220-1100nm while retaining
all of the characteristics of a concave grating spectrometer!!! In
addition, StellarNet offers a Dual Channel Spectrometer system for
spectroradiometry, the Dual DSR (Detector Super Range) combines a CCD
and InGaAs detector to cover a wavelength range of 200-1700nm for

Cosine Receptor Lens Assembly System (CR2 and
CRLENS) attaches to fiber optic cable and allow for absolute
calibration in radiance RADCAL-SR
The factory performs
calibrations for the appropriate
wavelength range of your spectrometer using NIST
traceable calibration lamps (calibration service RAD-CAL-SR must be ordered with spectrometer and proper measurement
accessories- fiber optic cable, CR2, and CRLENS)
Fast delivery: most system can be calibrated and shipped
within 1 week after receipt of order
Absolute calibration: accuracy within 10% at detector
integration setting used for calibration
documentation with NIST traceable serial numbers.
If the user has an appropriate irradiance
calibration source lamp, a field re-calibration can be easily
performed using the included SpectraWiz software.
Dual DSR Spectroradiometer-
Halogen-lamp spectra (300-1700nm).
StellarNet Dual DSR system pictured above uses a Y
bifurcated fiber (F600-Y-UVSRNIR)
to connect a
BLACK-Comet-SR spectrometer and a RED-Wave NIR Spectrometer.
The entire system can be radiometrically calibrated over the range
200-1700nm. Above system pictured with Flash Capture Interface (FCI)
that allows spectrometer to capture emission from flashing sources
such as flashtubes and pulsed solar simulators.
