This optical characteristic measurement device and method involve spectrally separating and measuring light to be measured by a first and a second spectrometric unit that have different accuracies, and calculating a certain optical characteristic of the light to be measured on the basis of the first and second spectrometric results, wherein the first and/or the second measurement angle of the first and second spectrometric unit can be changed by the measurement angle variable optical system. |
