Abstract
In a fluorescence detection type electrophoresis apparatus, comprising an electrophoresis separation gel plate (2, 102, 205), an excitation laser beam source (3, 201, 201) for emitting fluorescent light, and a fluorescent light detector (9, 109, 212) for detecting the emitted fluorescent light, a fluorescent light images are divided into a plurality of virtual images by an image divider (5, 7.sub.2, 104, 105, 209) and at the same time, the lights corresponding to the individual divided images are wavelength-selected by bandpass filters (8, 8.sub.3, 107, 108, 120, 227-230), thereby providing highly accurate, sensitive separation and detection of DNA fragments and the like and determination of base sequence of DNA and the like.
