The optical field has extremely high requirements for the optical performance, accuracy, and formability of materials, and polysilazane can precisely meet these needs and play a unique role in it.
In the manufacturing of optical lenses, polysilazane can be processed into various shapes and specifications of lenses through precision molding processes such as injection molding, compression molding, etc. It has good controllability of refractive index. By changing certain components in its molecular structure or processing parameters, the refractive index of the lens can be accurately adjusted to meet the requirements of different optical systems for light focusing, divergence, etc. For example, in camera lenses, polysilazane lenses can be combined with other optical glass materials to optimize the optical performance of the lens, improve imaging clarity, contrast, and color reproduction, and provide strong guarantees for photography enthusiasts and professional photographers to take high-quality photos.
As a key component in fields such as optical communication, optical waveguides have high requirements for material transparency, low loss, and compatibility with other optoelectronic devices. Polysilazane has become one of the ideal materials for manufacturing optical waveguides due to its excellent optical transparency and low optical propagation loss. It can construct high-precision optical waveguide structures on substrates such as chips through micro nano processing technologies such as photolithography and etching, achieving efficient transmission and precise control of optical signals, promoting the development of optical communication technology towards higher transmission rates and lower signal losses, and meeting the urgent needs of modern society for high-speed and high-capacity data communication.
Moreover, polysilazane also has applications in the field of optical thin films. In the preparation of optical thin films, uniform and dense thin films can be formed through processes such as solution spin coating and vapor deposition, which are used for the manufacture of different types of optical thin films such as reflective films and anti reflective films. These optical films can be applied to devices such as displays and solar photovoltaic panels to improve their optical performance, such as increasing the viewing angle of displays and enhancing the light absorption efficiency of solar photovoltaic panels. They have played a positive role in promoting the development of the optoelectronic industry.
