Microscope with electronic image sensor

A microscope comprising:

• a light source;
• a stage for placing a specimen irradiated with light from said light source;
• an imaging optical system which faces the specimen on said stage, and acquires an observation image of the specimen;
• an image sensing element provided at an imaging position of said imaging optical system;
• a control unit for controlling said image sensing element;
• a shutter mechanism disposed along an optical path between said light source and the specimen, and 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 eight source coaxially with the observation optical system;
• and
• a light-transmitting dustproof member interposed between said light source and said semi-transmission reflecting member,
• wherein said shutter mechanism includes a mechanical shutter interposed between said light source and said light-transmitting dustproof member.

A microscope comprising:

• a light source;
• a stage for placing a specimen irradiated with light from said 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 said observation optical system of said lens barrel that 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 base disposed on a surface of a desk;
• a support member which stands substantially upright on said base;
• a substantially cylindrical cover which covers said light source, said stage, said observation optical system, said lens barrel, said image sensing element, said electrical processing unit, and said support member;
• recording means for recording the image data of the observation image;
• zooming lenses provided in said observation optical system, and which rotate to change an observation magnification of the microscope;
• and
• a zooming handle which projects from a side surface of said substantially cylindrical cover, for rotating said zooming lenses,
• wherein said light source, said stage, said lens barrel, and said image sensing element are arranged in a substantially vertical line within said substantially cylindrical cover, an opening for insertion/removal of the specimen and a display surface of said monitor are provided in the side surface of said substantially cylindrical cover, and said recording means is detachably provided on an upper surface of said substantially cylindrical cover.
