An erect movable objective lens type optical microscope includes a frame, an observation optical portion having an objective lens, a stage portion, a moving mechanism, and a vibration synchronizing mechanism. The observation optical portion is movably provided on the frame, and the stage portion is fixedly provided on the frame. The stage portion includes a specimen moving stage, and a stationary stage adapted to receive a manipulator for manipulating a specimen provided on the specimen moving stage. The moving mechanism is provided on the frame for moving the observation optical portion and the stage portion relative to each other, and the vibration synchronizing mechanism is provided for synchronizing a vibration system of the stationary stage and a vibration system of the specimen moving stage.

Movable objective lens type optical microscope having stationary stage

A microscope has an optical system in which the number of photographing optical paths can be increased. The optical system includes a light source, an illuminating optical system for radiating the illuminating light to a sample, an objective lens which is opposed to the sample, an imaging lens, which is arranged in an optical path of light passed through the objective lens, a first beam splitting block, arranged in an optical path between the objective lens and the primary image, for splitting the light passed through the imaging lens into at least three different directions, a second beam splitting block for splitting one of the light split by the first beam splitting block into a plurality of directions, an observation optical path which receives the light split by the second beam splitting block, and a plurality of photographing optical paths provided for the split light, wherein images of the same magnification are formed.

Microscope

Detection data of an amount of control is directly monitored and a correction control command is directly outputted by a plurality of numerically controlled drive units 4, 5, 6 via the common sending line 3 and the common receiving line 2 without using NC 1. When a dedicated communication line 30 is used, detection data of an amount of control is directly monitored and a correction control command is directly outputted without using NC 1. The data is processed by the numerically controlled drive units 4, 5, 6 which are controlled and driven at a higher speed than the speed determined by the control cycle of NC 1, and the synchronizing control is carried out.
