ABSTRACT:
A microplate reader includes a light emitting portion for irradiating each of a plurality of test samples with excitation light, a light receiving portion for receiving return light from each of the test samples, an XY stage for moving the light emitting portion and the light receiving portion to traverse and scan the test samples, and a display portion for radiating visible light of a visible quantity in response to detection of fluorescence emitted from the test samples. An operator determines whether the measured test sample has emitted fluorescence based on illumination of the display portion.
