The Stellar-RAD SpectroRadiometer is an easy to use research grade spectrometer for field testing of lights with no additional setup required. The NIST traceable system can measure spectral Irradiance & Illuminance, Correlated Color Temperature (CCT), xy Chromaticity, PAR and more!

StellarNet’s handheld spectroradiometer systems put the power of a complete NIST traceable light laboratory in your hand allowing measurements of optical power, color, and spectral analysis for numerous lighting applications. All Stellar-RAD Systems are rugged in design with no moving parts making measurements in the field or on site quick and easy.

Compared to other handhelds, the Stellar-RAD contains research grade optics with <1nm spectral resolution making these instruments the first choice in reliable testing, field demonstrations, installations, R&D and quality control. Additionally, its modular design allows for use with StellarNet’s line of integrating spheres and accessories for Total Lumen measurement.
