Abstract
The multi-colored electrophoresis pattern reading system compares the patterns of electrophoresis without a warp to be caused upon electrophoresis by reading the patterns of electrophoresis which is carried out concurrently for plural samples and by labelling the samples with fluorescent substances having different fluorescent wavelengths. The patterns of electrophoresis are read by allowing fluorescence to emit from the plural samples. In reading the fluorescent patterns, optical signals are received by the light receiving section and then the fluorescence having a predetermined wavelength is separated by the fluorescent-wavelength separating section from the optical signals with the aid of an optical filter capable of controlling an angle of incidence relative to the optical axis of the optical filter. The optical signals passed through the fluorescent-wavelength separating section is then subjected to optoelectrical conversion into electric signals which in turn are subjected to signal processing, thereby converting the electric signals into a desired form of data representation.
