LUMINESCENT CHARACTERISTIC MEASURING DEVICE OF LIGHT EMITTING BODY

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive measuring device that guides a plurality of light emissions (light emissions of a light emitting body) in a test space in parallel with a plurality of optical fibers, and measures all light emissions only by arranging fewer light receiving means. SOLUTION: The luminescent characteristic measuring device of the light emitting body comprises: a plurality of first optical fibers 110A for transmitting light of an organic EL element 140 arranged in thermostatic chambers 121-124 to the outside of the thermostatic chambers 121-124; an optical switch 114 that is arranged out of the thermostatic chamber 121-124 and whose input side is connected to the plurality of first optical fibers 110A; second optical fibers 110B that are connected to the output side of the optical switch 114 and fewer than the first optical fibers 110A; and a spectrometer 116 that is connected to the second optical fibers 110B and receives the transmitted light.
