Mirrors in Imaging成像中的镜子
Mirrors are used widely in optical instruments for gathering light and forming images since they work over a wider wavelength range and do not have the problems of dispersion which are associated with lenses and other refracting elements. 镜子在光学仪器中被广泛使用,用于收集光并形成图像,因为它们在更宽的波长范围内工作,并且不具有与透镜和其他折射元件相关的色散问题。

Mirror Instruments镜像仪器
Mirrors are widely used in telescopes and telephoto lenses. They have the advantage of operating over a wider range of wavelengths, from infrared to ultraviolet and above. They avoid the chromatic aberration arising from dispersion in lenses, but are subject to other aberrations. Instruments which use only mirrors to form images are called catoptric systems, while those which use both lenses and mirrors are called catadioptric systems (dioptric systems being those with lenses only). 镜子广泛用于望远镜和长焦镜头中。它们的优点是可以在更宽的波长范围内工作,从红外到紫外以及更长的波长。它们避免了由于透镜色散引起的色差,但会受到其他像差的影响。仅使用镜子成像的仪器称为猫眼系统,而同时使用透镜和镜子的仪器称为猫眼-透镜系统(仅使用透镜的系统称为透镜系统)。
