摘要
硫系玻璃作为红外光学系统的基础材料,在夜视枪瞄、车载夜视、星际生命探测等高端红外光学领域应用前景十分广阔。硫系玻璃的优点是折射率温度系数低,可避免光学系统的热失焦,实现系统色差自校正,并保证成像质量;缺点是色散系数大,实际应用时需要将其加工成面形复杂的元件。现有元件加工技术难以满足高精度、多品种、小批量硫系玻璃光学元件的加工需要。增材制造是一种迅速发展的新型制造技术,适于复杂结构器件的个性化定制。将增材制造技术用于硫系玻璃光学元件制备,对于解决硫系玻璃发展中遇到的瓶颈问题,促进硫系玻璃的快速发展具有重要意义。重点探讨了增材制造技术用于制造硫系玻璃光学元件的可行性并分析未来发展前景。
Chalcogenide glass,a fundamental material for an infrared optical system,is widely used in high-end infrared optical fields such as night vision riflescope,car night vision and star life detection.The advantage of the chalcogenide glass is the low refractive index temperature coefficient,which help optical system avoiding thermal focus,realizing the self-correction of the system chromatic aberration,and then ensuring the image quality.The disadvantage of the chalcogenide glass is the high dispersion coefficient make the chalcogenide glass need to be processed into complex surface elements in practical application.However,the normal existing manufacturing technologies can not meet the high precision,multi-species,small batch processing need of optical elements.The additive manufacturing technology is a rapid development of new manufacturing technology,which is suitable for complex structural components.This paper focuses on the feasibility analysis of the additive manufacturing technology used in the processing chalcogenide glass optical elements,and explore the development prospects.The results will be helpful to solve the bottleneck problems in preparation for chalcogenide glass optical elements and improve its engineering development.
