【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。
[Abstract]:Sulfur glasses, as the basic materials of infrared optical system, have a broad application prospect in the field of high end infrared optics, such as night vision gun, vehicle night vision, interstellar life detection, etc. The advantage of sulfur glass is low refractive index temperature coefficient. The thermal defocusing of optical system can be avoided, the color difference self-tuning of the system can be realized, and the imaging quality can be guaranteed. The disadvantage is that the dispersion coefficient is large and it needs to be machined into complex facet elements in practical application. The existing component processing technology is difficult to meet the needs of high precision and variety. The manufacture of small batch sulfur glass optical elements is a rapidly developing new manufacturing technology. It is suitable for individualized customization of complex structure devices. The technology of adding material is used to fabricate optical elements of sulfur glass, which can solve the bottleneck problem in the development of sulfur glass. It is of great significance to promote the rapid development of sulfur glasses. This paper mainly discusses the feasibility of fabricating the optical components of sulfur glasses by means of material increasing technology and analyzes the future development prospects.
