Description
The StellarRAD™ Series 3 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 handheld colorimeters, the StellarRAD utilizes a research-grade spectrometer 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 Software Interface
Take a tour of our StellarRAD Pro software delivered on our new series 3 StellarRAD Handheld SpectroRadiometer. This quick demo shows how to connect to the device, modify Device Settings (integration time, scans to average, smoothing), take a dark reference, capture sample data, and save and review spectral data! This quick demo is just the beginning of the spectrum as the StellarRAD also features Episodic Data Capture, PDF reporting, and much more!
Light Hurricane Demo
The intuitive StellarRAD software interface allows system control and collection of advanced light measurement parameters such as spectral irradiance (Watt/m²), illuminance (lumen/m²), & PAR (Photosynthetically Active Radiation). Colorimetric analysis such as CRI (Color Rendering Index), CCT (Correlated Color Temperature), xy chromaticity, and much more are included. Capture snapshots or continuous mode spectra. Easily save and export your data and full spectral graph as an .IRR text data file, screenshot, and/or PDF report with all parameters listed.
StellarRAD Applications – LEDs, Luminaires, Solar, Displays, Grow Lights, & Lasers!
Any Light Emission
What better way to demonstrate a handheld radiometer than to measure a candle flame! Any type of light emission can be measured by pointing the StellarRAD’s cosine receptor toward the light source, setting the best exposure time and system settings, and pressing capture.
White LED Color
White light, cool white, warm white, incandescent white, LEDs… Just how many different white lights can there be? The StellarRAD automatically calculates Correlated Color Temperature (CCT) and Color Rendering Index (CRI). Easily distinguish and compare white LEDs.
LED Quality Control
With so many LEDs being manufactured overseas, you need a reliable instrument to test your incoming products. As a manufacturer or product integrator, checking the power and wavelength for accuracy of specification and/or consistency is important. The StellarRAD is the instrument for you.
