description PURPOSE:To obtain an observation image of uniform brightness even when the liquid surface in a wall is in a concave lens shape by arranging light emission bodies which emit nonparallel light as a light source so that at least some of light beams from the respective light emission bodies are almost parallel to the optical axis of an objective in an object of measurement. CONSTITUTION:The light emitting diodes 5a are arranged in plane in contact with one another to form a matrix-shaped lattice. By this arrangement, the light beams from the respective light emitting diodes 5a are almost parallel to the optical axis of the objective in the liquid in the wall 2b. Namely, nonparallel light beams from light emission bodies are projected on the object of measurement to perform uniform lighting even if the object of measurement is in a concave lens shape owing to surface tension, the observation image has nearly uniform brightness irrelevantly to the position in the well, and an accurate observation is therefore made by the simple constitution.
