OPTICALLY MEASURING METHOD, AND METHOD AND DEVICE FOR MEASURING LIGHT EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To obtain a light source with known spectral absolute photon flux with a simple method. SOLUTION: Outgoing light of a spectral light source 100 having a lamp 1, converging optical systems (lenses) 2 and 4 and a spectroscope 3 is measured by a light detector 5 with a known quantum efficiency, and the spectral absolute photon flux of the spectral light source 100 is determined based on the measurement results. This light source is used as a light source with known spectral absolute photon flux. Calibration of a spectrometric device is performed by use of this light source with known spectral absolute photon flux to measure spectral characteristics of a light emitting element such as an OLED.
