Embodiment Construction

[0027] Embodiments of the present invention will be described below with reference to the accompanying drawings. However, the embodiments described below do not limit the technical scope of the present invention.

[0028] figure 1 is a schematic diagram showing a microscope according to one embodiment of the present invention, here partially cut away to illustrate its internal construction. According to the microscope of the present invention, the image of the specimen placed on the stage 8 is magnified by the objective lens 9, the light beam from the objective lens 9 is bent by the lens barrel 12, and then guided to the eyepiece 14 connected to the observation element 13, thereby performing Observed.

[0029] The microscope frame 1 is provided with a vertical movement handle 16 for changing the distance between a specimen placed on the stage 8 and the objective lens 9 by moving the stage 8 in the vertical direction. Also disposed on the stage 8 is a stage handle 15 for mov...

Abstract

A microscope which is capable of quickly switching different methods of observation such as phase contrast observation and bright field observation. The microscope comprises a condenser lens for condensing an illumination light, a diaphragm disposed on the optical axis of the condenser lens and having a variable aperture area, an aperture setting means for setting the an aperture area of the diaphragm, a slider disposed on the light condensing side of the condenser lens and having a first aperture portion having a ring slit and a second aperture portion, a first control means for restricting the aperture area to the full open aperture side when the first aperture portion is disposed on the optical axis of the condenser lens, and a second control means for releasing the restriction on the aperture portion when the second aperture portion is disposed on the optical axis of the condenser lens.

Description

technical field [0001] The present invention relates to a microscope, and more particularly, to a microscope equipped with a slider provided with a condenser lens and the like including an annular diaphragm for observation of phase contrast so that various observations including bright field observation and phase contrast observation can be performed . Background technique [0002] In the field of biological microscopes, various observations including phase contrast observation and dark field observation are performed in addition to ordinary bright field observation for observing specimens by illuminating light. "Phase contrast observation" here refers to an observation method in which illuminating light is irradiated onto a translucent specimen of cells or the like through a slit so that the interference of the primary light passing through the specimen and the secondary light scattered by the specimen, The translucent specimen is visualized. "Dark field observation" refe...
