The surface of the optical film is smooth, and the interface between the film layers is geometrically divided; the refractive index of the film layer can jump at the interface, but it is continuous in the film layer; it can be a transparent medium or an absorbing medium; it can be The normal direction is uniform or the normal direction is not uniform. The actual film is much more complicated than the ideal film. 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, which leads to the diffuse scattering of the light beam; the interpenetration between the film layers forms a diffusion interface; due to the growth of the film layer, The anisotropy of the film is formed due to the structure, stress and other reasons; the film has a complicated time effect. Optical films are classified into reflective films, antireflection films, filter films, optical protective films, polarizing films, spectroscopic films, and phase films according to their applications. The first four are commonly used. Optical reflective film is used to increase specular reflectivity and is commonly used to manufacture reflective, refractive and resonant cavity devices. The optical anti-reflection coating is deposited on the surface of the optical element to reduce surface reflection and increase the transmission of the optical system. It is also called anti-reflection coating. Optical filter films are used for spectral or other optical segmentation, and they have many types and complex structures. The optical protective film is deposited on the surface of metal or other soft and erodible materials or thin films to increase its strength or stability and improve optical properties. The most common is the protective film of the metal mirror. The application of optical film is everywhere, from the coating of glasses to the LCD of mobile phones, computers, TVs to LED lighting and so on. It fills all aspects of our lives and makes our lives more colorful. Generally, the preparation conditions of optical films are demanding and precise, and sometimes they need to be carefully designed and analyzed. There is a software that is very powerful, it can 'take everything' in the design and analysis of optical films. This TFCalc optical film software can be used to design various types of anti-reflection, high-reflection, band-pass, spectroscopy, phase and other film systems. First of all, it supports the modeling of various film systems. TFCalc can design the base double-sided film system, the single-sided film layer can reach up to 5000 layers, and supports the input of the film stack formula. And can simulate various types of illumination: such as cone beam, random radiation beam and so on. Secondly, it has a certain optimization function, which can optimize the reflectance, transmittance, absorptivity, phase, ellipsometric parameters and other objectives of the film system by methods such as extreme value and variational method. Needle method can also be used, as long as the initial single-layer film can automatically design various film systems.
