An optical microscope of the transmission type for illuminating a sample according to the bright-field illumination method and for observing light passing through the sample includes a microscope body, objectives attached to the microscope body and having an optical axis, a stage serving to support the sample facing the objective used and attached, movable along the optical axis, to the microscope body, and a plane fluorescent lamp unit attached, movable along the optical axis, to the microscope body and serving to bright-field illuminate the sample through the stage. The unit includes a container provided with transparent panels, plane fluorescent layers formed on inner faces of the upper and lower panels of the container and spread substantially perpendicular to the optical axis.

Ultrasonic microscope

A microscope equipped with an electric device for driving a revolver and a stage, having a means capable of rotating the revolver to interchange an objective only when a stage is lowered by a constant amount, a means capable of changing the movement speed of the stage for focusing in accordance with the magnification of the objective brought into a light path, and a means capable of restoring to an original position after the stage is once lowered to a lower limit position in order to be able to focus simply and rapidly and perform securely the interchange of the objective and the like. The electric device involves a step motor and, except when the stage is being driven, the connection between the motor and the stage is released so that the stage may be easily controlled by a manual operation.
