Abstract:
An ultraviolet microscope capable of switching between visible light observation and ultraviolet light observation, comprising:an illumination system for illuminating a specimen with one of visible light and ultraviolet light, the ultraviolet light having a wave length of 300 nm or less; a shading device for preventing the ultraviolet light from being cast on the specimen, the shading device being located in the ultraviolet light illumination system; a shading drive device for driving the shading device; an observation system for observing the specimen, the observation system having an optical path; an electromotive turret for supporting a visible light objective lens and an ultraviolet light objective lens, and for selectively positioning the objective lenses in the optical path; a turret driving device for driving the electromotive turret; an instruction device for instructing switching between the visible light observation and the ultraviolet light observation; and a control unit for triggering the shading drive device to block the ultraviolet light and subsequently triggering the turret driving device to switch to the visible light objective lens when the instruction device instructs to switch from the ultraviolet light observation to the visible light observation.
