Observation device

Abstract

An observation device configured to observe a sample stored in a multistage container including a plurality of spaces divided by a plurality of partition walls which are parallel. The observation device includes: a light source configured to generate light; a phase contrast microscope configured to irradiate the sample with light from the light source and to make executable observing a phase difference due to interference of light returned from the sample; and a reflection mirror configured to reflect light passed through the sample again toward the sample. The reflection mirror is inclined with respect to the plurality of partition walls of the multistage container.
