摘要
平行光管是光学实验室常用的光学精密仪器,通过光源照射靶标模拟无穷远目标,是光学系统装调、测试必需的设备。设计了一个有效口径为200 mm、焦距为5000 mm的平行光管,采用离轴两反射式系统结构,视场角为0.35°,主次镜都为非球面,次镜为凸双曲面,系统中心视场波像差设计值达到1/62λ,边缘视场波像差设计值达到1/21λ。对该平行光管次镜检验方案进行了研究,提出了一种简单可靠的凸双曲面次镜正面检验方案。
The collimator is a commonly used optical precision instrument in optical laboratory,it simulates an infinite target by illuminating the target with the light source,which is the necessary equipment for assembly,adjustment and testing of optical system.A collimator with 200 mm aperture and 5000 mm focal length was designed and off-axis two-reflective system structure was used,and the field angle was 0.35°.Both primary and secondary mirrors were aspherical and the secondary mirror was convex double-curved surface.The design value of system center field-of-view wave aberration was 1/62λ,and that of edge field-of-view wave aberration was 1/21λ.The inspection scheme of secondary mirror of this collimator was studied,and a simple and reliable front testing scheme for convex double-curved surface secondary mirror was proposed.
