Removing secondary spectrum in wide spectrum optical system

  • 摘要: 利用修正的部分色散(P)和阿贝数(V)公式,计算一些典型的普通光学玻璃在450nm~950nm波段的色散特性,应用二级光谱理论,采用普通光学材料,设计了一个复消色差系统,分析近红外波段光学系统的二级光谱特性及校正方法,给出设计实例。设计结果表明:在可见光近红外波段,采用重冕玻璃ZK4、ZK8和特种火石玻璃TF3组合实现了二级光谱色差的校正,即从理论的0.18mm减少到0.084mm,证明该系统有较好的消色差能力,并且具有较长的后截距,为安装像移补偿反射镜提供了方便。
    Abstract: The partial dispersion of some typical glasses working on near infrared band was calculated with the formulas in which P and V were modified. The apochromatism of a wide band system was designed and analyzed. The result shows that the combination of the heavy crown glasses ZK8, ZK4 and special flint type TF3 is effective to correct secondary spectrum. Zonal chromatic aberration of the optical system is decreased from theoretic 0.18mm to 0.084mm in wide spectrum. The rear cut-off length of optical system is long enough for the reflector to image shifting compensation.
