REACTION TREATMENT DEVICE

WIPO Patent Application WO/2020/008972

A1

This reaction treatment device is provided with: a reaction treatment container 10; a first optical head 51 provided with a first objective lens OB1 that irradiates a sample with first excitation light while concentrating first fluorescent light generated from the sample; a second optical head 55 provided with a second objective lens OB2 that irradiates a sample with second excitation light while concentrating second fluorescent light generated from the sample; and a holding member 61 for holding the first optical head 51 and the second optical head 55. The wavelength range of the first fluorescent light and the wavelength range of the second fluorescent light at least partially overlap. The distance P between the optical axis of the first objective lens OB1 and the optical axis of the second objective lens OB2 satisfies 2·P0+2·P1+4·P2+4·P3
