| StellarNet Releases New low cost Solar Measurement System
StellarNet announces a new SpectroRadiometer system designed to characterize and evaluate light emissions according to industry standards used for solar simulators and a variety of applications.
The complete NIST traceable system consists of a portable UV-VIS-NIR fiber optic spectrometer and fiber light receptor. 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.
As photovoltaic cell manufacturers are driven to obtain higher production volumes and increased cell uniformity requirements, high performance solar simulation is a necessity. There are many companies offering high performance solar simulator lamps these lamps provide the cell manufacturer measurement uniformity, comparability, and traceability. Likewise, organizations such as IEC, JIS, and ASTM have developed standards that define solar simulator performance in three key performance areas: spectral match to the solar spectrum, spatial uniformity of irradiance, and temporal stability.
SpectraWiz® also includes a multitude of radiometric and spectral analysis tools and calculations. User customizable SpectraWiz® LabVIEW programs and Excel programs for operation from Visual Basic Automation are included with every system. StellarNet miniature spectrometer systems are designed rugged with permanent alignment and no moving parts for shockproof and portable reliability. Plug and play USB-2 connection and powering options allows for ultimate measurement flexibility in any testing environment. |

StellarNet proudly introduces StellarSpheres, a new line of spectroradiometrically calibrated integrating spheres designed specifically for the low cost light measurement market.
These new spheres, when coupled with a StellarNet spectrometer, provide NIST traceable characterization of all types of light including discrete LEDs, LED arrays, and standard bulbs of various sizes and output intensities. The spheres are extremely robust yet are surprisingly lightweight, compact, and easy to operate.
All StellarNet integrating spheres are spectroradiometrically calibrated using NIST traceable lamps. Measurements include absolute intensity in Watts/m2, Lumens/m2, Radiant/Luminous Flux, Correlated Color Temperature (CCT), xy chromaticity, Color Rendering Index (CRI), dominant wavelength, and more across the 300-1700nm wavelength range.
The StellarSphere-IS6 is a 6” diameter integrating sphere with a 2.0” input port, internal reflective coating, baffle system, and SMA fiber optic output. This low cost sphere is available for $1745.
For internal device mounting, the StellarSphere-IS12, a 12” diameter integrating sphere, features a vertical hinge that opens to allow access to the sample stage. The sample stage is equipped with powered device mounting sockets with a variety of detachable socket options. In addition, the StellarSphere-IS12 includes a tungsten halogen lamp and data file for system calibration using the SpectraWiz® radiometer application software.
Due to the rapid growth of the LED industry, there is a need now more than ever for low cost light measurement equipment. Currently, the only commercially available systems are expensive, bulky, and complex to operate. Thus LED characterization and analysis has been limited mostly to high end R&D. StellarNet, a leading manufacturer of low cost spectrometer equipment worldwide since 1993, has finally responded to this increase in demand. The new lines of StellarNet StellarSphere systems, are lightweight, moduler, easy to use, and will surely fit your budget! |
