A cell observation system, for measuring fluorescence emitted from a cell held by a microplatehaving a plurality of wells, comprises a microplate holderfor mounting the microplate, an electrical stimulatorarranged with a plurality of electrode pairsincluding positive and negative electrodes, a position controllerfor controlling a position of the electrical stimulatorso as to place the electrode pairswithin the wells, a moving image acquisition unitfor detecting the fluorescence from the sample S within the wells, and a data analyzerfor setting a part of a region facing the positive electrodeon the wellas an analysis region and analyzing an optical intensity in the analysis region so as to acquire analysis information concerning the sample S.

Cell observation device, and cell observation method

The present invention relates to a light irradiation apparatus and the like which can reduce background light noise from a plurality of wells provided on a microplate. The light irradiation apparatus comprises a microplate, a light guiding member, and a light source apparatus. The light guiding member includes a plurality of light emitting units provided on a main surface in correspondence with the plurality of wells. Each light emitting unit includes depressions each having an opening on the main surface. Measurement light from the light source apparatus is inputted from a side surface, refracted and reflected at the side surface of each depression, and then outputted from the opening of each depression.
