Calibration of Photometer

Secondary Calibration Standards
(four-pieces, certified, REF 090-064)

for testing the photometric accuracy and linearity in the visible range regularly.

These secondary calibration standards were calibrated against normals which precision is based on national or international normals or was reached by derivation from calibrating techniques.

The secondary calibration standards consists of neutral density glass filters A, B, C und D. Standard A is used for the setting to zero.

Every secondary calibration standard set is delivered together with a calibrating protocol with readings of the standards determined in a calibrated spectral photometer at the wavelength 546 nm.
