Calibrated Deuterium and Tungsten Halogen light sources / Light sources

These light sources are radiometrically calibrated. They are used to calibrate the absolute spectral response of a spectrometer system

Calibrated Deuterium and Tungsten Halogen light sources summary

These stable calibrated light sources used with our software provide consistent absolute intensity values across UV, Visible and NIR wavelengths.

They are calibrated to deliver a known quantity of light with very low uncertainty.

The digital calibration data can be loaded into the software for absolute intensity data.
