Abstract
The invention relates to an optical standard () for the calibration or characterization of optical measuring devices and as a reference system for intensities and intensity measurements. The standard () according to the invention, constructed sandwich-like, comprises a combination of at least two layer-like optical standard modules () having defined optical properties, joinable or joined together plane-parallel, wherein the standard modules () in each instance differ from each other by at least one optical property, namely, by their absorption, emission, scatter and/or reflection properties, and the standard modules () are made so that they enter into physical interaction with electromagnetic radiation striking one of their two principal surfaces ().
