Description
技术领域technical field
本发明涉及硫系玻璃制备技术领域，尤其涉及一种用于硫系玻璃元件的3D打印装置。The invention relates to the technical field of chalcogenide glass preparation, in particular to a 3D printing device for chalcogenide glass components.
背景技术Background technique
硫系玻璃是指以元素周期表ⅥA族元素S、Se、Te为主并引入一定量的其他元素所形成的玻璃。相对于氧化物玻璃而言，硫系玻璃具有较大的质量和较弱的键强，是一种优良红外光学材料，光谱透过范围(0.9～15μm)。硫系玻璃作为一种红外光学材料，在红外波段透过光谱范围宽、光热特性稳定、化学稳定性优异、性能连续可调、制备成本低，并且与单晶锗等红外晶体材料在一些性能上具有互补性。在红外光学部件设计中，热差系数低硫系玻璃和高热差系数晶体材料组合用于红外光学系统中，可极大丰富红外光学材料的选择范围，增加系统设计的灵活性，简化系统结构，更为重要的是可显著改善系统在不同环境下(-55℃～130℃)的成像质量，提升红外热成像等光学系统的温度自适应性能，满足系统无热化设计要求，因此，硫系玻璃被视为新一代温度自适应红外光学系统核心透镜材料，可广泛应用于夜视枪瞄、红外肩扛导弹、战机夜视巡航、汽车夜视、安防监控等红外系统，市场前景巨大。Chalcogenide glass refers to the glass formed by the elements of group VIA of the periodic table of elements S, Se, and Te as the main elements and a certain amount of other elements introduced. Compared with oxide glass, chalcogenide glass has larger mass and weaker bond strength, and is an excellent infrared optical material with a spectral transmission range (0.9-15 μm). As an infrared optical material, chalcogenide glass has a wide transmission spectrum in the infrared band, stable photothermal characteristics, excellent chemical stability, continuously adjustable performance, and low preparation cost. are complementary. In the design of infrared optical components, the combination of chalcogenide glass with low thermal difference coefficient and crystal material with high thermal difference coefficient is used in the infrared optical system, which can greatly enrich the selection range of infrared optical materials, increase the flexibility of system design, simplify the system structure, More importantly, it can significantly improve the imaging quality of the system in different environments (-55°C to 130°C), improve the temperature adaptive performance of optical systems such as infrared thermal imaging, and meet the requirements of system athermalization design. Glass is regarded as the core lens material of a new generation of temperature-adaptive infrared optical systems. It can be widely used in infrared systems such as night vision gun sights, infrared shoulder-fired missiles, fighter night vision cruises, car night vision, and security monitoring. The market prospect is huge.
在硫系玻璃应用时，需要将其加工成形面复杂的光学元件来消除自身较大色散系数对光学系统的影响。目前，硫系玻璃元件加工最常用的方法有传统磨削加工、金刚石单点车削以及精密模压成形等三种方式。其中，传统磨削加工周期长，成品率低，材料利用率低，无法加工复杂形面光学元件如衍射非球面；金刚石单点车削可以加工复杂形面的光学元件，精度高，但材料利用率和加工效率低，成本高；精密模压成形适宜复杂形面光学元件的批量成形，但是精密成形模具成本过高，满足产品多样性的能力较差。In the application of chalcogenide glass, it is necessary to process optical elements with complex forming surfaces to eliminate the influence of its large dispersion coefficient on the optical system. At present, the most commonly used methods for processing chalcogenide glass components include traditional grinding, diamond single-point turning and precision molding. Among them, the traditional grinding process has a long cycle, low yield, and low material utilization rate, and cannot process complex-shaped optical elements such as diffractive aspheric surfaces; diamond single-point turning can process complex-shaped optical elements with high precision, but the material utilization rate is low. Low processing efficiency and high cost; precision compression molding is suitable for batch forming of optical components with complex shapes, but the cost of precision forming molds is too high, and the ability to meet product diversity is poor.
