CL7 UV Spectral Irradiance Standard (fully enclosed)

The CL7 is a universal UV spectral irradiance standard lamp for the calibration of spectroradiometers and radiometers. It is housed in a metal enclosure with optical bench compatible mounted holes in the base. Calibration distance is set using a spacer bar supplied with the lamp.

The calibration is performed with respect to National Physical Laboratory (NPL Teddington UK) calibrated lamps held by Bentham. Alternatively, direct NPL calibration can be offered.

706 power supplyThe CL7 is fitted with a 30W deuterium lamp and is supplied with a matched power supply, model 706.
