Preferred Label : optical-beam error;
Detailed label : optical-beam error in spectrochemical analysis;
IUPAC definition : For wavelength-scanning spectrometers, an error may be introduced if the image position
on the photodetector changes. Reflection of the incident radiation, e.g. between the
cell walls, is another source of error and results in a measured absorbance slightly
higher than the true absorbance. These errors are collectively termed optical-beam
errors.;
