In a microscope, an optical system that includes a zoom lens unit having a straight optical axis is located under a stage portion that carries a sample A thereon. An optical image of the sample A is projected on an image-pickup element via the optical system, and is converted into a picture signal by means of the image-pickup element. The picture signal is delivered to the outside through an external terminal area.

Microscope

According to the present invention, there is provided a microscope system comprising an illuminating portion which illuminates a subject, an image forming lens which projects the subject illuminated by the illuminating portion onto an image pickup element, a light adjustment portion which adjusts a light amount of the illuminating portion, a zoom mechanism which changes a magnification of a subject image projected onto the image pickup element by the image forming lens, and a control portion which changes an excitement pulse width into the illuminating portion in synchronization with a driving pulse of the image pickup element in response to adjustment by the light adjustment portion to control the light amount of illumination light and which varies the excitement pulse width in accordance with the change of the magnification by the zoom mechanism.

Microscope system

A microscope includes a column which stands upright on a base, an LED light source, a stage for placing a specimen irradiated with light from the LED light source, a lens barrel which is arranged to face the specimen on the stage, and has an observation optical system for acquiring the observation image of the specimen, an image sensing element which is arranged at the imaging position of the observation optical system of the lens barrel, and senses the observation image of the specimen, a monitor for displaying the observation image sensed by the image sensing element, and a recording unit for recording image data of the observation image sensed by the image sensing element. At least the LED light source, stage, observation optical system, and image sensing element are arranged along the optical axis of the observation optical system, and supported along the column.

Microscope with electronic image sensor

An illumination apparatus for an optical instrument includes an illumination section for outputting illumination light, and a lens made of rubber and arranged on the optical path of the illumination light output from the illumination section.

Illumination apparatus for optical instrument

A microscope stage comprising an upper stage and a lower stage provided on a preset microscope and overlapped on each other in a vertical direction, said upper stage being disposed to move in a straight direction with respect to said lower stage, a pair of pulleys disposed on one of said upper stage and said lower stage and arranged with a preset distance in a direction parallel to the movement direction of said upper stage, and an endless driving force transmission member stretched between said pair of pulleys and reciprocally moved between said pulleys.
