Radiometrically calibrated light sources from Ocean Insight are used to calibrate the absolute spectral response of a spectrometer system. With the HL-3P-CAL light source and our software, you can determine absolute intensity values across Vis-NIR wavelengths.

Radiometrically calibrated light sources are carefully characterized to deliver a known quantity of light with very low uncertainty. Each source is measured to NIST-traceable standards, creating an unbroken chain of traceability and providing you with the highest quality and most reliable data.

The HL-3P-CAL is radiometrically calibrated for use with a cosine corrector (CC-3), which is included. Also, the HL-3P-CAL can be calibrated for use with an optical fiber, which requires purchase of the fiber and our calibration service.


  • Calibrated for use with cosine corrector -- radiometrically calibrated and shipped with CC-3 cosine corrector
  • Optional calibration for use with optical fiber -- additional charge for radiometric calibration with fiber
  • Vis-NIR wavelengths -- radiometrically calibrated source for ~350-1100 nm
  • Digital calibration data -- can be loaded into software for absolute intensity data
  • Application flexibility -- measure LEDs, digital displays and other radiant sources
