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.

Fitted with a high performance 30W deuterium lamp, the entrance optic of the spectroradiometer is simply 'plugged in' to a highly-reproducible position using an interchangeable adaptor. A range of such interchangeable adapters accommodate Bentham's range of transmission diffuser and integrating sphere entrance optics.

Stable lamp operation may be ensured in operating the CL7 with the 706 deuterium lamp supply.
