Abstract

The invention discloses a device for preparing an optical component by a sol and a preparation method thereof. The device comprises a sol preparation device, a sol mixing bin, a sol stirrer, a high-pressure gas generator, a laser irradiation device, a substrate carrying table and a computer control system; a raw material preparation device is communicated with a raw material mixing bin; a raw material sitter is arranged in the raw material mixing bin for further stirring of a mixed sol raw material; the high-pressure gas generator sprays the mixed sol raw material onto a substrate arranged above the substrate carrying table through a spray nozzle formed in the tail end of the high-pressure gas generator; the laser irradiation device is arranged above the substrate in an aligning manner. Through the preparation method disclosed by the invention, the optical component is directly prepared by the sol; sol raw material solution mixing, coating of a sol layer on the surface of the substrate and sol layer laser sintering are completed according to different types of optical components, and further, the component preparation is completed. The shape and the size of the optical component prepared by the device and the method are controllable, so that the preparation time of the component is greatly saved, and the quality and the precision of the component are improved.

Description

technical field [0001] The invention belongs to the technical field of optical element preparation, and in particular relates to a device for preparing optical elements from sol and a preparation method thereof. Background technique [0002] The preparation of traditional optical components is mostly obtained by high-temperature sintering of powder materials in a mold of a certain shape. The preparation of the powder requires a complicated process, and the dispersion of the added materials in the powder is not uniform, which eventually leads to poor optical performance of the optical element. In recent years, with the development of preparation technology, a method of photocuring rapid prototyping has emerged, such as the method of photocuring rapid prototyping for optical components proposed by Li Dongfang, Institute of Laser Engineering, Beijing University of Technology, and others. However, the material of optical components targeted by this photocuring technology is mai...
