Abstract
A microscope for observing a specimen immersed in an immersion liquid within a specimen container includes an objective lens and utilizes a sealed container containing a second liquid that has substantially the same refractive index as the immersion liquid. The sealed container is positioned between the objective lens and the specimen. Alternatively, the microscope for observing the specimen immersed in the immersion liquid can utilize a container opening toward the objective lens. A method of observing the specimen includes the steps of positioning a container containing a liquid, with substantially the same refractive index as an immersion liquid within a specimen container, between a microscope objective lens and the specimen and observing the specimen through the objective lens.
