中文摘要: 为满足双波段、大孔径、紧凑结构的设计要求,设计了一种中、长波红外共光路的折射式光学系统,通过使用分色镜来分离中波红外和长波红外的光谱,然后连接到分别校正像差的镜头组件上。该系统的工作波段覆盖中波3.7~4.8 μm,长波10.3~12.5 μm,中、长波红外系统焦距均为216 mm,视场角均为2°×2.5°,焦距与通光口径之比为2,满足100%冷光阑效率。仿真表明该系统成像质量优良,公差合理,具备较强的工程可行性。

Abstract:To satisfy the design requirements of dual-band operation, large aperture, and compact structure, a refractive optical system with a common optical path for mid-wave and long-wave infrared was developed. The mid-wave and long-wave infrared wavebands are separated using a dichroic filter and subsequently directed to respective lens components that correct for aberration. This system operates within the mid-wave infrared band (3.7~ 4.8 μm) and the long-wave infrared band (10.3~12.5 μm). Both the mid-wave and long-wave infrared systems have a focal length of 216 mm, a field of view of 2°×2.5°, and a ratio of focal length to aperture diameter of 2, while achieving 100% cold stop efficiency. The imaging performance is excellent, with feasible tolerances and good engineering feasibility.
