摘要：The invention relates to a method and an associated device for verifying thetransmittance of a flat-glass substrate (40) with a measuring device (10), with which lightof at least one light source (20) is guided from one side of the flat-glass substrate (40)through the flat-glass substrate (40) to the opposite side of the flat-glass substrate (40),where it is captured by at least one receiving unit (30) and the transmittance of the flat-glass substrate (40) is determined by means of a comparison between the intensity ofthe light emitted by the light source (20) and the light incident upon the receiving unit(30). In a first measurement, a light source (20) generates polychromatic light in theprocess, wherein the transmittance is determined at a point of the flat-glass substrate(40), and in at least one further measurement, a light source (20) generates

monochromatic light of a defined wavelength, the transmittance also being determinedat the same point of the flat-glass substrate (40), if possible. By comparing the at leasttwo measurements, it is determined whether the transmittance is approximately thesame or not the same in all measurements, in order thus to be able to better narrow

down the cause for a reduced transmittance.
