Standaarden voor kleurreferentie en spectroscopie

Colour reference and spectroscopy standards are used to routinely monitor optical spectrometer mechanisms. The calibration solutions provide the base readings that users can compare with the electromagnetic radiation wavelengths and intensities scientific instruments obtain. Placing the reference solution inside, users can zero out settings to re-establish proper mechanics and eliminate systematic error. For quality control, the colour reference and spectroscopy standards guarantee that the machines function properly for accurate spectral lines.
