CMS has designed a portable spectral irradiance source (200 W), based on the prototype of the PTB (Physikalisch Technische Bundesanstalt, Braunschweig). Technical improvements allowe a simple and quick change of the lamps (tungsten halogen) by up keeping of the original lamp certificate.

CMS will offer the spectral irradiance standard DLS-J1016. The Deuterium Lamp System DLS-J1016 is a newly developed transfer standard for spectral irradiance in the UV wavelength range from 200 nm to 350 nm. It is based on a design by the Physikalisch-Technische Bundesanstalt (PTB), Germany.

CMS offers the LED Transfer Standard LED-J1019. It is a new developed device for photometric and colorimetric units such as luminous flux [lm], luminous intensity [cd], dominant wavelength, based on a design by the Physikalisch-Technische Bundesanstalt (PTB), Germany.

The accuracy of any spectroradiometric measurement system can only be as good as that of the standard source used for calibration. We manufacture a range of sources calibrated in our laboratory using NPL calibrated versions of the same product.

The following table is a representative but not complete list of devices available:
