[0028] figure 2 A method for obtaining the preparation parameters of the graded-refractive-index film provided by the first embodiment of the present invention is shown, and the method is used to obtain the preparation parameters of the graded-refractive-index film. Gradient-refractive-index film refers to a film whose refractive index changes continuously along the normal direction of the film surface and remains constant in the direction parallel to the film surface. Rugate film is a kind of graded index film, which refers to a film whose refractive index layer changes periodically as the thickness of the film layer increases. Special optical properties can be achieved through periodic changes in the refractive index, such as the property of reflecting only a narrow spectral region while transmitting other wavelength bands. In the following embodiment, the method for obtaining the preparation parameters of the graded-refractive-index film provided in the embodiment of the ...

Abstract

The invention provides a gradual change refraction-index film preparation parameter obtaining method, a preparation method and a light filter and belongs to the technical field of film preparation processes. The preparation parameter obtaining method comprises the steps that preparation data of a gradual change refraction-index film to be prepared is obtained, wherein the preparation data includes refraction index and thickness of each film layer of the gradual change refraction-index film; a standard correspondence relation is obtained, wherein the standard correspondence relation is the relation between the refraction index of a hybrid film layer and film layer concentration; according to the standard correspondence relation and the preparation data, preparation parameters of the gradual change refraction-index film are obtained. By adopting the method, accurate obtaining of the preparation parameters of the gradual change refraction-index film to be prepared is promoted, and accordingly the gradual change refraction-index film and the light filter which meet the demands in performance are prepared.

Description

technical field [0001] The invention relates to the technical field of thin film preparation technology, in particular to a method for obtaining preparation parameters of a graded refractive index thin film, a preparation method and an optical filter. Background technique [0002] Wrinkle (Rugate) filter refers to a structure with regular periodic changes in refractive index. Through this periodic change, special optical properties can be achieved, such as having only a narrow spectral region of reflection, while passing through all other The nature of the band. This property is similar to the 1 / 4 wave pile, and there is no high order reflection band of the 1 / 4 wave pile, especially suitable for removing bright spectral lines in a weak continuous spectral background, such as laser spectral lines, so in such as laser protection, etc. There are important applications in the field. [0003] However, at present, the core technology for the preparation of graded-index films is ...
