DEVICE AND METHOD FOR OBSERVING BIOCHEMICAL SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To provide an observing device and an observing method capable of accurately and rapidly focusing a biochemical substance stuck to a container and highly precisely and efficiently observing the biochemical substance. SOLUTION: A focusing mark M which is a reference position at the time of focusing at the focus position F0 of an optical system 13 is provided at the transparent outer bottom surface 8b of the well 8 of a plate 7 to store the biochemical substance 12 and a focus moving amount F1 equivalent to a distance between the focusing mark M and a desired observing position is previously obtained, and the focus is moved by only the focus moving amount F1 after the optical system 13 is focused at the focusing mark M at the time of performing the focusing so as to observe the biochemical substance 12, so that the focusing is accurately and quickly performed even in the case of observing an object whose observing image is unclear.
