Description
The StellarRAD is a rugged, turn-key solution for portable light measurement. This handheld radiometer 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, CCT, xy chromaticity, CRI, PAR and much more!
Compared to other handhelds, the StellarRAD contains our research grade spectrometers with <1nm spectral resolution making these instruments the first choice in reliable testing, field demonstrations, installations, R&D, and quality control.
- Reliably measure light output in Lumens/m^2 (Lux), Watts/m2, PAR, PPFD, and Footcandles
- 1931 CIE Chromaticity Diagram for xy Chromaticity, Dominant Wavelength, Purity, Correlated Color Temperature (CCT), & Color Rendering Index (CRI)
- Includes NIST Certificate of Traceability and delivered with all calibrations preloaded ready to use
- UV upgrades (250-1100nm) available; includes UVa, UVb, UVc, ratios, & power for $500
- Includes Solar Monitoring App with solar and grow light classification
- Add lens, aperture, and collimating tube attachments for increased functionality
- StellarRAD+Color Handheld Colorimeter upgrade now available
Handheld SpectroRadiometer for NIST traceable light measurement from 350-1100nm with <1nm spectral resolution. UV and near-infrared ranges are optional. Handheld-Radiometer measures irradiance, illuminance, xy chromaticity, dominant wavelength, CCT, CRI, the complete spectral distribution of all light 350-1100nm, and much more! The handheld system incorporates research-grade BLUE-Wave spectrometer optics. It has an 8", high performance Android touchscreen interface that’s both ergonomic and user-friendly. System comes with pre-installed StellarRAD software and calibration, direct attach SMA-coupler, CR2 Cosine Receptor, IRRAD-CAL irradiance calibration, and certificate. System charging adapter and USB key included.

NIST Calibrations
The factory performs calibrations for the StellarRAD using NIST traceable calibration lamps for absolute intensity in Watts/m^2/nm. Absolute calibration: accuracy within 10% at detector integration setting used for calibration.
IRRAD-CAL Certificate is included which contains all pertinent NIST traceable calibration information.
Optional RAD-CAL-SR or Radiance calibration (W/m^2/sr) can be purchased with your StellarRAD. This type of calibration is often purchased when measuring display screens and backlights. Must also purchase the CRLENS accessory.
Other calibrations can also be purchased with each StellarRAD system. Contact your local technical sales representative for the best configuration for you.
