ことで自動的にフォーカシングを行っている。An example of using a microscope having such an autofocus mechanism is, for example, chromosomal diagnosis in which a large number of specimens are diagnosed. In this case, an infrared reflection film is formed on a portion adjacent to a chromosome of a slide (cover glass, slide glass) that holds a chromosome (an example of a sample). And a microscope with an autofocus mechanism
For example, an optical system including an infrared light source, a lens that forms an infrared ray from the light source on the reflective film surface, a lens that re-images the reflected light from the reflective surface, and a light receiving element at the imaging position of the lens. And has an optical system that can move integrally with the objective lens, and automatically detects the output of the light receiving element (which becomes an autofocus signal) and optimizes the position of the objective lens for automatic focusing. ing.

FIG. 3 is a schematic cross-sectional view showing an example in which the cover glass having an infrared reflective film formed thereon is applied and spread on the sample with the reflective film surface on the sample side with an encapsulant interposed therebetween. In this example,
There will be no problem if the specimen and the infrared reflective film on the lower surface of the cover glass are in close contact, but in reality, when the thickness of the embedding liquid (mounting medium) of the specimen is large or impurities such as dust are present between the specimen and the infrared reflective film. When sandwiched between the two, the focus position shifts between the sample and the infrared reflection film, and there is a problem that accurate autofocus cannot be achieved.
