Optical standard for calibrating Spektralmess systems

Examples of an optical standards, and a calibration apparatus for calibrating or characterizing a spectroscopy system using such an optical standards are disclosed. The optical standard may comprise a mixture of acetaminophen and barium sulfate, with a mass of the acetaminophen in the mixture is less than a mass of the BaSO Such an optical standard may be used in a calibration apparatus for calibrating or characterizing a spectroscopy system. The calibration device may comprise a substrate base having a top and a bottom. The top surface may include a section for receiving the optical standard sample. The receiving section may be adhesively. The calibration apparatus may further comprise a film that is attached to the top surface of the substrate base, in order to cover at least the section of the substrate where the optical standard is placed. The calibration device can be disposed of after the calibration measurements have been completed. The optical standard and calibration apparatus using the optical standards may as a wavelength calibration standard to calibrate a Raman system, as a reflection reference standard for a Reflexionsspektralmessung or for a functional capability test in a Fluoreszenzspektral system may be used.
