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

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.
