OPTICAL ELEMENT AND LIGHT CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical element which exhibits significant light response (variation in reflectance) with low-density light power and to provide a light control method. SOLUTION: A dielectric layer 1, an organic dye layer 2 which is sensitive to light of a specified wavelength and reversibly varies refractive index under light of different wavelengths and a reflecting layer 3 are stacked in order.
