Abstract:
PROBLEM TO BE SOLVED: To provide an optical measuring instrument for easily and optically measuring a flat measuring surface even if the amount of a liquid or molten material being a measuring target is little and for measuring the physical properties of the liquid or molten material by causing no transpiration or no reaction with another substance, and an optical measuring method. SOLUTION: The optical measuring instrument includes a base transparent container 6 which houses a measuring target material and keeps at least the base 6a flat and transparent and an optical device which projects light on the base 6a of the container 6 and detects and measures the reflected light 11 from the base. The base of the transparent container 6 housing the liquid or molten material 13 is irradiated with incident light 10 from a light source 1 and the reflected light component from the liquid or molten material 13 in the reflected light 11 is detected and measured.

Abstract:
PROBLEM TO BE SOLVED: To provide a weak luminescence detecting device, in luminescence measurement, capable of: preventing dark current values or dark current pulse numbers from reducing and from fluctuating relative to temperatures; capturing luminescence signals at a high solid angle; and detecting with high sensitivity luminescence having no directivity such as chemiluminescence or bioluminescence.SOLUTION: A luminescence measuring apparatus comprises: a plate-like member for holding a holder for a container storing a sample; a luminescence detection part for detecting luminescence in the sample; a temperature control part for controlling temperature of the luminescence detection part; and an air blowing part for blowing air to a luminescence receiving surface of the luminescence detection part.
