ABSTRACT:
An ultraviolet microscope comprises an observation device which observes a specimen with ultraviolet light; a gas supply device which, during the observation with ultraviolet light, supplies an inert gas to surroundings of the specimen; and a timing control device which controls supply timing of the inert gas by the gas supply device, and the timing control device controls the gas supply device so as to cause preliminary supply of the inert gas before the observation of the specimen with ultraviolet light, and also so as to cause regular supply of the inert gas at least during the observation of the specimen with ultraviolet light.
