Abstract

PURPOSE: To separate quantity of incident light over the entire visible light region of wavelengths 380 to 700 nm to transmitted light of 50% and reflected light of 50% by alternately laminating layers of a high refractive index and layers of a low refractive index to 6 layers from the substrate side and specifying their optical film thicknesses.
