Ultra-precision machining of optical parts

From childhood to mobile phones with one hand, to televisions and computers in daily life, to military industry and aerospace in the field of national defense, the demand for optical components has become increasingly widespread with the development of modern science and technology. More and more precision instruments are used in the new technology of the combination of opto-electromechanics, which has promoted the realization of increasingly stringent requirements of multi-function, high performance and low cost, and promoted the development of traditional optical parts production technology and the transformation of processing technology. . This change has promoted the development of optical technology in two different directions. First, develop towards small, light and inexpensive high-efficiency processing. Second, develop towards ultra-precision machining. For example, the optical systems of manned spaceflight, laser weapons, optical fiber communication components, and micro-optical parts in optical integrated circuits are all ultra-precise optical parts. The processing precision of these optical parts even reaches the nanometer level. The processing of these parts cannot be achieved by traditional methods, and can only be achieved through ultra-precision processing technology. The traditional processing method of optical parts has a history of more than a hundred years, and it can be widely understood as 'a handful of sand and a handful of water'. The new optical parts processing method began in the 1970s. The military optical system has expanded from white light to infrared and laser systems. For optical parts, it is also difficult to achieve good image quality, small size, light weight, and simple structure. Require. Following the large-scale technological revolution and innovation activities in the optical processing industry, new optical parts processing methods continue to emerge.
