Optical film design and development

>< /> :r= d Optical film design and development
How much does optical film cost? This question has caused doubts in quite a few people! With the rapid development of the mobile Internet, high-power laser anti-reflection film manufacturers are also booming, and optical film development companies are springing up like mushrooms after a rain. Their technical strength and after-sales service vary widely. Since the year, the excellent technical performance of optical films of the Optical Film Technology Research Center has been widely welcomed by the market. As a product with stable products and excellent technology in the industry, the last special reminder is: when choosing an anti-reflective film developer , Never cooperate with irregular developers just for the sake of cheap prices. This approach will only damage your own interests. Cooperating with regular developers can reduce a lot of unnecessary troubles, and at the same time ensure a long-term, good and sustainable cooperative relationship in the future.

The characteristics of optical films are: the surface is smooth, and the interface between the film layers is geometrically divided. The refractive index of the film layer can undergo a jump at the interface, but it is continuous within the film layer and can be a transparent medium. It is also possible that the absorbing medium can be normal or non-uniform. Practical thin films are much more complex than ideal ones. This is because: during preparation, the optical and physical properties of the film deviate from the bulk material, and its surface and interface are rough, resulting in diffuse scattering of light beams. The interpenetration between the film layers forms a diffusion interface due to the growth and structure of the film layers. , stress and other reasons, the anisotropic film layer forming the film has complex time effects.
Optical films are divided into anti-reflection films, anti-reflection films, filter films according to their applications.
Main content
An important type of optical components. This field mainly includes the following aspects:
①Research on the optical properties, mechanical properties and other related properties of thin films
②The growth of thin films, the structure of thin films and their influence on the properties of thin films
/> ③ Design, preparation and performance testing of optical thin film components, etc.
◆Optical films are used everywhere, from glasses coating to LCD displays of mobile phones, computers, TVs to 3D lighting, etc. It fills every aspect of our lives and makes our lives more colorful.
◆The definition of optical film is: it involves the thin and uniform dielectric film layer attached to the surface of the optical device during the propagation path of light, and the reflection, transmission (refraction) and refraction when passing through the layered dielectric film layer. Polarization and other characteristics to achieve the special forms of light we want, such as full transmission of light, total reflection of light, or polarization separation of light in a certain or multiple wavelength ranges.
◆Optical thin films can be divided into geometric optics and physical optics. Geometric optics is a geometric dielectric film layer formed on the surface of an optical device to change the optical path to achieve the adjustment or redistribution of the light beam. Physical optics is the adjustment or redistribution of the light beam. The unique optical material elements in nature are nano-processed to form a dielectric film layer on the surface of the required optical device. The characteristics of the optical material elements passing through the dielectric film layer are enhanced to change light polarization, transmission, reflection and other functions.
◆Usually, the preparation conditions of optical films require high and precise requirements. The preparation of optical films is divided into dry preparation methods and wet preparation methods. Dry preparation methods (including vacuum coating: evaporation plating, magnetron sputtering, ion plating, etc.) It is generally used for the preparation of physical optical films. Wet preparation methods (including coating methods, casting methods, thermoplastic methods, etc.) are generally used for the preparation of geometric optical films.
