Working principle of milky membrane
Opal film is a common covering material, its working principle is mainly through light scattering and interference effect to achieve light reflection or transmission, has certain optical properties and application value.
Opal film is a thin film formed by tiny particles suspended in a transparent matrix, which usually transmits Milky White light. Its main working principle involves light scattering and interference effects.
First of all, the size of the tiny particles inside the opal film is usually equivalent to the wavelength of light. When light enters the opal film, these particles will scatter the light, so that the light waves of various colors are mixed together to form white. This is one of the reasons why the milky white film appears Milky White.
Secondly, the tiny particles in the opal film will have multiple reflections and refractions after the light enters, resulting in interference. Due to the irregular size and spatial position of the particles, different light rays will travel different paths, resulting in a change in phase, which eventually forms an interference light pattern at the observer. This interference effect also contributes to the special optical effect of the opal film.
Opal film has a wide range of applications in real life, such as packaging materials, decorative materials and optical devices have a unique value. Through in-depth understanding of the working principle of milk white film, this material can be better designed and applied to meet the needs of different fields.
In short, the working principle of opal film is based on the scattering and interference effect of light, through the complex interaction of small particles in the transparent matrix to achieve light reflection or transmission, showing a unique Milky White and optical effect.
