Apparatus and method for observing biochemical substance

Abstract

An apparatus and method for efficiently observing a biochemical substance with focusing accurately and rapidly on the substance disposed on an inside of a container is provided. A focusing mark, which is used as a reference when a focal point of an optical system is adjusted, is disposed on the outside of a transparent bottom of each wells in a micro plate. A focus-shift-distance corresponding to a distance between the mark and a desired position to be observed is determined. The optical system focuses on the mark, and then, the focal point the optical system is shifted by the focus-shift-distance. This shift allows an object to be focused on accurately and rapidly even when unclear images are obtained.
