Description

Technical Field

[0001] The invention relates to an infrared sulfur-based ultra-precision glass compression molding device and a use method thereof. Background Art

[0002] In recent years, as the bottleneck of chalcogenide glass research has been continuously broken through, its cost has gradually decreased, making it possible to widely use infrared thermal imagers and infrared detectors. Therefore, chalcogenide glass has been rapidly applied and developed in the military and civilian fields, and chalcogenide glass has begun to show excellent potential in the application of infrared materials. In the field of infrared optics, chalcogenide glass is considered to be the most promising material to replace single crystal germanium. It can not only form glass with chalcogenide elements or with chalcogenide elements, but also form a network of chalcogenide glass by combining chalcogenide elements with germanium, arsenic, silicon, aluminum, gallium, bromine, phosphorus and other elements. Compared with the former, this type of multinary chalcogenide glass has a series of more important and excellent properties; With the continuous deepening of research on chalcogenide glass and the advancement and application of its preparation technology, chalcogenide glass is increasingly widely used in infrared optical materials. Aspheric surfaces, binary diffraction surfaces and other technologies are gradually applied to the design of chalcogenide glass lenses, and quality requirements such as surface accuracy and appearance grade are becoming higher and higher. Therefore, domestic mainstream optical manufacturers such as Ningbo Sunny Infrared Optics and Dongguan Yutong Optics have adopted the mechanical processing method of single-point diamond lathe turning to produce chalcogenide glass lenses. Single-point diamond lathe equipment is expensive and inefficient. Precision molding technology can realize the mass production of chalcogenide glass lenses, improve the surface accuracy of the material and the qualified rate of the product, reduce the production cost of the material, and is suitable for large-scale production; When the existing ultra-precision glass molding device is in use, the liquid storage tank and the mold thereon are mostly of fixed sizes and are fixed to the molding device for use by bolts.
