Standard source in deuterium CL3

The open-frame deuterium CL3 spectral irradiance reference standard is used for accurate and traceable spectroradiometer calibration.

Calibrated in our specialist laboratory with regard to the standards calibrated by the Physicalish Technische Bundesanstalt (PTB, Germany), calibration is provided over a range of 200 to 400 nm.

The CL3 is equipped with a high-performance 30 W deuterium lamp, which matches the 706 power supply.

Mounting holes compatible with the optical bench located at the base of the CL3 standard source facilitate positioning, while the calibration distance is set at a distance of 200 mm using a spacer. The CL3 can be used with an optional BenFlection diffuse reflectance slab and support to provide a traceable energy luminance standard.
