The fluorescence microscope 100 comprises: a fixed-type objective lens 50 placed between a filter set and a specimen loading portion; a partition 47 that covers at least the specimen loading portion, the objective lens and the filter set to block extraneous light incident on the specimen loading portion; an imaging lens 52B arranged on the outgoing surface of the absorption filter of the filter set, the imaging lens including a zoom lens capable of continuously changing the operation distance; and an imaging portion forms a fluorescent image from a fluorescence emitted from the specimen and received by the imaging lens via the absorption filter by irradiating an excitation light onto the specimen from the excitation light source via the excitation filter of the filter set and. This configuration avoids damage to the specimen or lens surface while allowing high-contrast fluorescence observation with reduced effect of extraneous light. |
