Culture observation vessel and observation device

摘要

A culture vessel (30) having a base section (31) made from a plastic material of a columnar or frusto-conical shape. A side wall (32) is attached to the base section (31) of the vessel to form a basin over the upper surface of the base section (31). The base section (31) acts as an optical wave guide capable of guiding light between the upper and lower surfaces of the base section (31). The lower surface of the base section (31) may be optically connected to the light-entrance window (116) of an image pickup device (11).
