Abstract
The present invention provides a biochip reader for reading the image information of samples using a photodetector device, by irradiating a corresponding beam of excitation light at each site of a biochip on which a plurality of the samples are arranged at equal pitches, the biochip reader comprising: a microlens substrate provided with a plurality of microlenses to transform excitation light to be irradiated at the biochip into a multibeam; and a zoom lens located between the microlens substrate and the biochip and capable of projecting the multibeam while adjusting the pitch between sites of the biochip to the pitch of the multibeam. The present invention further provides a fluorometric imaging apparatus for detecting the image of a specimen by irradiating excitation light at samples on the specimen arranged in a two-dimensional manner and measuring fluorescent light produced from a fluorescent substance attached to the specimen, the fluorometric imaging apparatus comprising: a two-dimensional photodetector device for detecting excitation light passing through the specimen or reflecting off the surface thereof; and movement means for repositioning the specimen according to images observed on the photoreceptor device.
