Title: Inverted confocal microscope

Abstract: An inverted microscope is provided that reflects an observation light passing through an image-formation optical system upward using at least one reflection optical system and that leads the observation light to an observation path. The inverted microscope includes a confocal scanner arranged at an image surface position of the image-formation optical system, a light source for applying light onto a sample through the confocal scanner and the image-formation optical system, and a confocal image formation optical system that leads the light passing through the confocal scanner to the sample through the image-formation optical system, returns a return light from the sample to the confocal scanner along a route opposite to that for leading the light to the sample, and obtains a confocal image. A confocal observation optical system is also provided for leading the return light from the sample passing through the optical scanner to the observation optical path.
