Overview
The DH-3 Series of Halogen Calibrated Light Sources for the UV-VIS-Shortwave NIR (230nm-1100nm)
is a deuterium and halogen light source that provides known absolute intensity values at several
wavelengths, expressed in µW/cm²/nm. Since the spectral intensity of the DH-3 Series can be traced to an
intensity standard traceable to the National Institute of Standards and Technology (NIST), it is
specifically designed for calibrating the absolute spectral response of your system.
Note
If you have a spectrometer setup that is highly sensitive, you may not be able to use the
DH-3 Series as a calibration source.
