A method and device for the optical scanning of a chromatographic sample (3), where a sample plate (2) holding the sample (3) is illuminated with light from a first illumination device (13) and the light emitted by the sample plate (2) is detected by an optical detector device (15) which detects in cell form or area form, a second illumination device (14) is preferably firstly activated in a preparation step. The sample plate (2) is displaced in a first displacement direction relative to the detector device (15), illuminated by the first illumination device (13) and a first measurement image is recorded. The sample plate (2) is displaced in a second displacement direction relative to the detector device (15), illuminated by the second illumination device (14), and a second measurement image is recorded.
A method for the optical scanning of a sample (3), where a sample plate (2) holding the sample (3) is, in a first measurement step, illuminated at least with light from a first illumination device (13) and the light emitted by the sample plate (2) is detected by an optical detector device (15) which reads line by line or field by field and a first measurement image of the sample plate (2) is recorded, where the sample plate (2) is displaced in a first displacement direction relative to the detector device (15), and where, in a subsequent second measurement step, the sample plate (2) is displaced in a second displacement direction relative to the detector device (15), illuminated by a second illumination device (14) and a second measurement image of the sample plate (2) is recorded, wherein the illumination devices (13, 14) and the detector device (15) are located above the sample plate (2) and the illumination devices (13, 14) extend over the entire width of the sample plate to be illuminated.
