Since July 1994, the Gigahertz-Optik calibration laboratory for optical radiation measurement quantities has been accredited by the DKD accreditation institution (Registration Number DKD-K-10601) actual DAkkS (D-K-15047-01-00) for the calibration of Spectral Irradiance. The ISO/IEC/EN 17025 (formerly ISO/IEC Guide 25, known as ANSI/NCSL Z540-1, and EN45001) accreditation assures the competency of calibration laboratories to carry out  specific tests or calibrations and forms the basis of the lab’s quality system.

For quartz-halogen lamps and incandescent sources in the power range from 250 W to 2000 W, spectral irradiance calibration with an official DAkkS calibration certificate is available. These lamps are calibrated against one G-O calibration laboratory  BN-9101 1000 W FEL Type quartz-halogen lamps (PTB calibration certification for wavelengths from 250 to 2500 nm). The reference sources are periodically recalibrated by the PTB.

Intercomparison measurements of the source under test, such as the BN-9101 (See Calibration Standards section), to a reference standard source are performed. The complete calibration procedure follows accreditation regulations and is confirmed by a DAkkS calibration certificate supplied with the calibrated source.

 

The KLD calibration of spectral irradiance produced by the test with DAkkS certificate is  performed according to fixed accredited calibration procedures and specifications. The calibration is limited for lamps between 250 to 2000 W in the wavelength range from 250 nm to 2500 nm. The calibration is done by direct comparison to a PTB Reference Standard and is confirmed in the official DAkkS calibration certificate  supplied with the calibrated source.
