ABSTRACT:
A confocal microscopic equipment comprising a light source, a flat plate provided with a plurality of apertures, a detector comprising a plurality of detecting cells, a beam splitter that makes the light beam from the light source incident to the flat plate by transmission or reflection and makes the output light from the flat plate plate to be reflected or transmitted to the detector, and an objective lens that makes the light beam passed through the apertures of the flat plate form light images on the sample and makes the return light from the sample focus on the flat plate, wherein the distance between light spots focused on the detector is equal to or less than twice the distance between the detecting cells, and whereby scanning of an irradiating light beam is not required.
