Product Family Description

  • Used to Measure Light Sources
  • Provides Quick Calibration of LEDs
  • NIST Certificate Included

Spectroradiometers are calibrated spectrometers with the correct geometry to characterize light sources. Our spectroradiometer has a quartz cosine receptor and is calibrated to measure absolute spectral irradiance of light sources. It can be used as a quick, handheld device to verify center, dominant, and centroid wavelengths, intensity, and color of LED and other light sources. In addition to LED calibration and color analysis, this spectroradiometer is useful for solar studies, photo-stability testing, and photobiology and photochemistry applications.

The spectroradiometer can be easily integrated in the field or lab environment with the plug and play USB 2.0/1.1 interface, auxiliary trigger capability, and easy to use Windows® 7, 8, 8.1, or 10 compatible software. The software allows timeline recording, data smoothing, color measurement, external pulsed light capturing, and other data handling functions.
