Abstract
As light is allowed to impinge from above a microplate M and an imaging unit(a line sensorand an imaging optical system), which moves in a scanning motion along the bottom surface of the microplate M, receives transmitted light, images of wells W formed in the microplate M are captured. The scope of imaging by the line sensoris greater than the diameter of at least one well W, or preferably, encompasses a plurality of wells. When the depth of field of the optical systemis 0.6 mm or less, the influence of reflection of side walls of the wells upon the images is reduced.
