Application field and classification of optical film-film supplier

The application field and classification of optical film. Optical film is a kind of functional film that uses the film's effect on light. Optical film can achieve spectral transmission, spectral reflection, spectral absorption and light reflection reduction and increase reflection in terms of changing light intensity. , Beam splitting, high-pass, low-pass, narrow-band filtering and other functions. There are many types of optical films. These films endow the optical components with various performances, and play an important or decisive role in realizing the functions of optical instruments and influencing the quality of optical instruments. Traditional optical film is an important part of modern optical instruments and various optical devices. By coating one or more layers of films on the surface of various optical materials, the light interference effect of light is used to change the intensity of transmitted or reflected light. , Polarization state and phase change. The film can be plated on the surface of various materials such as optical glass, plastic, optical fiber, crystal, etc. Its thickness can range from a few nm to tens or hundreds of μm. Optical film can get good firmness, optical stability, and relatively low cost. It hardly increases the volume and weight of the material. Therefore, it is the preferred method to change the optical parameters of the system. It can even be said that there is no modern optical instrument without optical film. And various optical devices. In the course of more than two hundred years of development, optical thin films have formed a complete set of optical theory—thin film optics. Optical films have been widely used in various optical devices (such as laser resonators, interference filters, optical lenses, etc.). Not only that, its important role in the field of optoelectronics is gradually being recognized. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
