摘要

A method for manufacturing a reflection film, comprising the steps of:Preparation of an optical medium with a reflecting surface and a refractive index n₀;Determining a wavelength λ of to reflective light;Determining of two different refractive indices ns₁ and ns₂ from two different materials, between which the reflection is to be arranged;Lamination of k (k is a positive integer) pairs of a first layer having a refractive index n₁ and a second layer having a refractive index n₂ on the reflecting surface of the optical medium, wherein a thickness of the first layer: (λ / 4 + (λ / 2) × n1)/n1where n₁ 0 or is a positive integer; and a thickness of the second layer: (λ / 4 + (λ / 2) × n2)/n2where n₂ 0 or is a positive integer;Determining a thickness d₃ a third layer with a refractive index n₁, which fulfills: d3 = d + (λ / 2n1) × N3where n₃ 0 or a positive integer..
