1. A microscope comprising:

  • an LED light source;

    a stage for placing a specimen irradiated with light from said LED light source;

    a lens barrel which faces the specimen on said stage, and which includes an observation optical system for acquiring an observation image of the specimen;

    an image sensing element provided at an imaging position of the observation optical system of said lens barrel, and which senses the observation image of the specimen;

    an electrical processing unit for processing an output signal from said image sensing element;

    a monitor for displaying image data of the observation image output from said electrical processing unit;

    a control unit for controlling an image sensing timing of said image sensing element;

    a shutter mechanism disposed along an optical path between said LED light source and the specimen, which shields incident light on said image sensing element in synchronism with an image sensing timing of said image sensing element controlled by said control unit;

    a semi-transmission reflecting member for irradiating the specimen with illumination light from said LED light source coaxially with the observation optical system; and

    a light-transmitting dustproof member interposed between said LED light source and said semi-transmission reflecting member, wherein said shutter mechanism includes a mechanical shutter interposed between said LED light source and said light-transmitting dustproof member.
