StellarNet announces its new all-in-one light measurement system, the SolarRad, for only $5,325

Instruments for Solar Monitoring The SolarRad (300-1100nm) and SolarRad-DSR (300-1700nm) spectrometer configurations are the perfect tools for making solar irradiance measurements of all kinds. They are popular tools for measuring solar simulators and artificial lighting for various solar energy, biological, and horticultural applications. The instruments are NIST calibrated to measure the spectral irradiance in units of watts per meter squared over the wavelength range in nanometers. The systems combine a BLACK-Comet concave grating spectrometer with a RED-Wave NIR instrument to capture a complete UV-VIS-NIR irradiance spectrum all in real time!  We have already chosen all the proper accessories, slit sizes, and calibrations that you may need and have packaged them into one system. You can also choose from a list of additional accessories and features to add to your system. StellarNet SpectroRadiometers – UV-VIS-NIR Ranges 200-2300nm – Low cost – Ruggedized high performance – Shock-proof – Permanently aligned – SpectraWiz Software included Free – Battery packs for field measurements – USB-2 interface to all notebook PCs


Most popular configuration. The SolarRad features everything needed to perform light measurements over the 300-1100nm wavelength range (with deep UV options available). At the heart of the system is the BLACK-Comet-CXR-SR concave grating spectrometer featuring a UV enhanced CCD detector.

The SolarRad-DSR or Dual-Radiometer system is configured for a wide range of solar spectral irradiance measurements from 300-1700nm. This configuration combines a BLACK-Comet or BLUE-Wave spectrometer with a DWARF-Star NIR instrument to capture a complete UV-VIS-NIR irradiance spectrum all in real-time!

Add UV Monitoring Capabilities The SolarRad typically comes configured for irradiance measurements >300nm using NIST traceable Tungsten Halogen Lamps. Add further UV capability to your system with an IRRADCAL-UV UV calibration to your system.  This additional calibration uses a NIST traceable deuterium source to provide UV measurements 200-400nm!

NIST Calibrations

StellarNet Calibration ServicesThe factory performs calibrations for the appropriate wavelength range of your spectrometer using NIST traceable calibration lamps (calibration service such as IRRAD-CAL must be ordered with spectrometer and proper measurement accessories) 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. Certificate available: 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. Calibrations are available for UV, VIS,NIR ranges and can be configured for spectral irradiance (W/m^2), radiance (W/m^2/sr) and total power in watt flux in Watts.

The factory performs several x-axis calibrations on all spectrometers and depending on customer application a StellarNet spectrometer may be calibrated also in the y-axis for absolute intensity measurements.  A y-axis Irradiance calibration is performed using NIST traceable lamps.  There are several available calibrations depending on your spectrometer wavelength range and slit size.

Solar Measurement Sample Spectra

Solar Match Monitor-
The SpectraWiz® software now includes a new solar match panel that is part of the Light Monitor application, that is used to characterize and classify light emissions for solar simulators. The Solar Match Monitor application calculates spectral irradiance for each 100nm bin from 400-1100nm and compares the results to the ideal percent for each bin range per IEC/JIS/ASTM. The proximity of the measured data to the ideal values results in classification of the solar simulator lamp from A through D. The Light Monitor also measures UVabc regions below 400nm using both U.S. and European standards.

Episodic Data capture of Sunset– Solar spectra was recorded periodically during sunset. The instrumentation used above is the standard BLACK-Comet model spectrometer, a F600 fiber optic cable, and a cosine receptor. Additionally, the spectrometer was spectroradiometrically calibrated for low light conditions using a NIST traceable lamp and receptor aperture. The episodic data capture shows clearly when the Sun has dropped over the horizon and the spectral signature of distant streetlights becomes the most significant feature of the spectrum. StellarNet solar monitors may also be used to test solar simulators and other artificial lights frequently used in the solar cell testing, production, and quality control.

Solar Match Monitor BLACK-Comet-CXR-SR 50um slit, F600VIS-NIR fiber, CR2 Cosine receptor, CR2-AP, CR2-TP and other optional accessories available to measure the sun or your solar simulator.

SpectraWiz UV monitoring can provide UVa, UVb, and UVc irradiance measurements as well as providing UVa/b ratios and other useful values.

Solar Monitoring Spotlight

Research in David Sedlak’s group at the University of California Berkeley includes the design of constructed wetlands for water and wastewater treatment. These constructed wetlands rely on maximizing sunlight exposure to remove organic contaminants through photochemical reactions. Reaction rates and mechanisms of contaminant removal are studied using simulated sunlight in the laboratory, and are then modeled under field conditions. In order to translate laboratory findings and predict contaminant removal in constructed wetland treatment systems, the research team relies on accurate and high resolution characterization of solar spectra both in the lab & field.

A StellarNet spectroradiometer provides the capacity to quickly and easily measure light intensity across the entire solar spectrum, generating critical information both for characterizing fundamental chemical reactions and for designing actual treatment systems.
