OPTICAL PRODUCT

Document Type and Number:

WIPO Patent Application WO/2018/110017

Kind Code:

A1

Abstract:

An optical product is provided which can achieve desired spectral characteristics while exhibiting a catalytic effect. This optical product has a glass substrate on which a multilayer film of three or more layers is formed, and by using a combination of at least one low refractive index layer and at least one high refractive index layer, the multilayer substrate can adjust the spectral characteristics of the optical product. The top layer furthest from the glass substrate is a low refractive index layer, and a high refractive index layer adjacent to the top layer is a functional layer having a metal oxide with a photocatalytic function as the main component, and satisfies the conditional expressions below. 60nm ≤ TL ≤ 350nm (1) 220nm ≤ Tcat ≤ 700nm (2) Here, TL is the film thickness of the top layer, and Tcat is the film thickness of the functional layer.
