Calibrated in our dedicated laboratory with respect to standards calibrated by the Physicalish Technische Bundesanstalt (PTB, Germany), calibration is provided over the range 200-400nm.

The CL3 houses a high performance 30W deuterium lamp matched to the 706 deuterium lamp supply.

Optical bench compatible mounting holes in the base of the CL3 facilitate positioning, whilst the calibration distance is set at a distance of 200mm using a spacer bar. The CL3 may be used alongside an optional Benflect diffuse reflectance tile and mount to constitute a traceable UV spectral radiance standard.
