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.

Dependent claims

A light-emission detection apparatus comprising:

a condensing-lens array in which M condensing lenses are arranged, for individually condensing lights emitted from a emission-point array in which M emission points are arranged, to form M light beams, where M≥2;
at least one sensor on which the M light beams are incident in parallel, wherein
when an average of effective diameters of the M emission points is d,
an average of focal lengths of the M condensing lenses is f,
an average of intervals of the M condensing lenses is p, and
an average of maximum optical path lengths between the M condensing lenses and the at least one sensor is g,
the d, f, p, and g satisfy relation f≥1/((2*p)/(1.27*d)+1)*g.
