Abstract
The phase contrast microscope includes: an illumination optical system 10 that emits illumination light for phase difference measurement to an observation target placed in a container; an adjustment optical system 20 that is provided between the illumination optical system 10 and the observation target S, has at least one optical element 21, and adjusts refraction of the illumination light due to a liquid surface shape of a liquid C in the container 60; an imaging unit 40 that images the observation target to which the illumination light has been emitted; and an adjustment optical system control unit 51 that adjusts optical characteristics of the adjustment optical system 20 based on uniformity of a density of an image captured by the imaging unit 40 and a density contrast.
Claims20
A phase contrast microscope, comprising:
- an illumination optical system that emits illumination light for phase difference measurement to an observation target placed in a container;
- an adjustment optical system that is provided between the illumination optical system and the observation target, has at least one optical element, and adjusts refraction of the illumination light due to a liquid surface shape of a liquid in the container;
- an imaging unit that images the observation target to which the illumination light has been emitted;
- and
- an adjustment optical system control unit that adjusts optical characteristics of the adjustment optical system based on uniformity of a density of an image captured by the imaging unit and a density contrast.
