Abstract
The invention is directed to a light-emission detection apparatus for individually condensing light emitted from each emission point of a emission-point array using each condensing lens of a condensing-lens array to form a light beam and detecting each light beam incident on a sensor in parallel, and the light-emission detection apparatus can be downsized and high sensitivity and low crosstalk can be simultaneously accomplished when a certain relation between the diameter of each emission point, a focal length of each condensing lens, an interval of condensing lenses, and an optical path length between each condensing lens and a sensor is satisfied.
