Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the drawings and examples.

[0019] Taking the coated glass with a double-layer film structure as an example, the film 1 and the film 2 are plated on the ordinary white glass substrate 3 in sequence, as shown in Figure 1, where I and R represent incident light and reflected light respectively. The materials of the two layers are different. The optical parameters of film 1 have been determined, and the refractive index n 1 And extinction coefficient k 1 The curve is shown in Figure 2, the thickness h 1 It is 274.6nm. Thin film 2 is the target layer that needs to be designed to eliminate the reflection color of the coated glass of this double-layer film structure, and its refractive index, extinction coefficient and thickness are respectively denoted as n 2 , K 2 And h 2 , And use a polynomial function with strong adaptability to expand n 2 , K 2 The dispersion relationship with the incident lig...

Abstract

This invention relates to a method for designing the coating of double membrane coated glass which can eliminate the reflective color, the steps show as follow: based on one kind of optical parameters of the coating, it creates the mathematics relationship between the optical parameters of double membrane coating and the reflective color's saturation of the coated glass to achieve the mathematics model, then it works out the optimization problem combining the annealing method with the Newton-Raphson method, the results gives the ideal optical parameters matching the coating.

Description

Technical field [0001] The invention relates to a film layer design method for coated glass, in particular to a film layer design method for eliminating the reflection color of a double-layer film structure coated glass. Background technique [0002] Coated glass is to coat one or more layers of metal, metal oxide or other inorganic materials on the surface of the glass to change the optical properties of the glass to meet certain specific requirements. As the coated glass for window glass applications, due to functional requirements, it often has a two-layer or more than two-layer film structure, while also meeting aesthetic requirements. Generally, this requires that the reflection color of the coated glass is colorless or a certain color that is stable and controllable. When light passes through a double-layer film or a multilayer film structure, the color will appear due to the interference of the film. For coated glass with double-layer film structure, the traditional proces...
