Product Details

Radiometrically calibrated light sources from Ocean Insight are used to calibrate the absolute spectral response of a spectrometer system. Using these light sources and our software, you can determine absolute intensity values across UV, Visible and NIR wavelengths.

An extended-range (to 2400 nm) calibration option is also available, for an additional fee. Contact us for details.

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.

Also, Ocean Insight offers radiometric calibration services performed at our ISO 17025-certified lab.


Product Overview

  • Stable sources -- provide consistent output for the most reliable data
  • Multiple options -- radiometrically calibrated sources for UV-Visible-NIR and Visible-NIR wavelengths; extended-range (to 2400 nm) option available for additional fee
  • Digital calibration data -- can be loaded into software for absolute intensity data
  • Applications flexibility -- measure LEDs, digital displays and other radiant sources
