ABSTRACT:
A laser microscope according to the present invention comprises a laser light source which generates a laser beam, an optical path split portion which has a plurality of optical path split elements with different characteristics for separating the laser beam irradiated to a sample from the laser light source and light returned from the sample and includes a selection mechanism to switch these optical path split elements on an optical path, an imaging lens to converge light which is returned from the sample and is separated in the optical path split portion, a spectrophotometric detection unit which obtains spectral data of light from the sample, an optical fiber which guides light from the sample imaged by the imaging lens to the spectrophotometric detection unit, wherein an incident end face of the fiber is arranged to a position substantially conjugate to the sample, and a transfer mechanism which moves an incident end face of the optical fiber in a plane orthogonal to an optical axis of light incident on the optical fiber.
