Problems solved by technology

After installation and use of various coating products used outdoors, sunlight is the light source, and most of them have a non-0° incident angle, so there will inevitably be changes in optical performance due to changes in the incident angle of the sun, and aggravate the optical uniformity of the product due to process fluctuations. sexual problems

Embodiment 1

[0042] Take magnetron sputtering plating large area solar selective absorption film as an example. The solar selective absorption film is mainly used for photothermal conversion. Its main goal is to absorb solar energy to the greatest extent and convert it into heat energy, so its main performance is solar energy. The higher the solar absorption rate, the better the product performance. Because the absorption rate is not easy to measure directly, and the solar selective absorption film is plated on the aluminum plate, its transmittance is 0. According to the principle of energy conservation, the product's absorption rate = 1-reflectance, so if the product's solar absorption rate The maximum is equivalent to the minimum solar reflectance. Table 1 shows the target configuration of the production line and the film sequence determined by it. The substrate is an aluminum plate with a thickness of 1mm; when magnetron sputtering is used to coat the solar selective absorption film, Al ...

[0063] The following uses an antireflection and antireflection film as an example. The anti-reflection and anti-reflection film is to increase the transmittance of the substrate and reduce the reflectivity by plating multilayer films with different optical constants on the surface of the substrate. The substrate can be transparent materials such as glass and resin. The performance of AR coating is mainly for visible light, so the wavelength range of the calculation and analysis is the visible light band of 380 to 780 nm. According to the characteristics of performance requirements, the visible light transmittance of the product film should be maximized. The present invention uses 3mm borosilicate glass as the substrate. Table 7 shows the target configuration of the production line and the film sequence determined by it. The production conditions prepare a total of 4 layers of antireflection and antireflection film, using Nb, Si NbOx and SiOx thin films were prepared by reactive...

Abstract

The invention discloses a multiangle spectral sensitivity analysis method for a film system and application of the method. The analysis method comprises the following steps: performing initial film layer thickness setting according to a product performance constraint condition under the condition that a film layer sequence and a film layer optical constant are determined; establishing a film system admittance matrix model, and converting a substrate and the film layer sequence, the film layer optical constant and the initially set film layer thickness of each thin film into a characteristic matrix; calculating the transmittance and reflectivity spectrum data of the film system by virtue of the combined characteristic matrix of the substrate and each thin film. According to the method, a reasonable film system thickness design range is established according to comprehensive performance requirements of the product and a production condition, and a reasonable and accurate film system structure admittance matrix optical model is established; the product spectral and optical performance of the film system under different incident angle conditions can be rapidly analyzed to obtain a film system structure with minimal optical performance changes in case of angle changes by virtue of a genetic algorithm.

Description

Technical field [0001] The invention relates to the technical field of coating optical performance, in particular to a method for analyzing multi-angle spectral sensitivity of a film system and its application. Background technique [0002] Improving the optical properties of the material is one of the main purposes of coating the surface of the material. For example, the selective solar absorption coating is to coat the surface of the aluminum plate with a multi-layer film that can effectively absorb the solar energy to convert solar energy into light and heat; The anti-reflection film system is used to alternately coat multiple layers of films with different optical constants on the glass surface to achieve the effect of reducing the surface reflection of the film and increasing the transmittance. The optical performance of the product can be evaluated by indicators such as visible light transmittance, solar transmittance, color, etc. These optical properties are the result of ...
