Overview
The DH-3PLUS Series of Light Sources for the UV-VIS-NIR (210nm-2400nm, depending upon
configuration) 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-
3PLUS 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.
Calibrated sources are guaranteed for the lesser of 50 hours of operation or 1 year from factory
calibration. Due to low usage for guaranteed calibration, they are not intended to be used as an
illuminant in day-to-day measurements.
If you have a spectrometer setup that is highly sensitive, you may not be able to
use the DH-3PLUS Series as a calibration source.
