DRUG DEVELOPMENT SCREENING DEVICE

PROBLEM TO BE SOLVED: To provide a drug development screening device capable of acquiring a multicolored confocal image by a simple optical system, wherein a confocal function is integrated with a spectroscopic function. SOLUTION: In this drug development screening device for irradiating excitation light to a sample placed on a well plate, and screening by performing image processing, based on a fluorescence signal from the sample, a multicolored confocal scanner is constituted by integrating in a body: a pinhole array disk with a microlens; a first dichroic mirror for transmitting the excitation light, and reflecting multicolored fluorescence; one or more second and third dichroic mirrors for spectrally diffracting the multicolored fluorescence; a plurality of band-pass filters for taking out fluorescence having a single wavelength from a multicolored fluorescence signal; and relay lenses, arranged respectively on the subsequent stage of the plurality of band-pass filters.
