您要查找的是不是：
- Aspherical lenses, which have nonspherical curvature, are inserted between the usual spherical lenses so light is focused uniformly on all pixels, improving sharpness. 通常把镜片曲率不是球形的非球面镜片，置于球面镜片之间以调整光线，让焦点落在像素上，用来改善影像清晰度。
- They are demonstrated based on single spherical lens. 在此基础上进而研究开发了计算机辅助光学作图系统。
- The preceding chapter, for the most part, dealt with paraxial theory as applied to thin spherical lens systems. 前一章讨论的基本上是应用于薄球面透镜系统的傍轴理论。
- We can draw such a conclusion that the Galilean beam expander with an asphericcal lens is better than that with a spherical lens. 我们得出的结论是：伽里略非球面透镜扩束器比伽里略球面透镜扩束器好。
- The lensometers is also called measural lens dioptre instrument,to measure spherical lens dioptre,cylindric lens dioptre and axis,prism dioptre,and lens optical center etc. 顶焦度计又称对光机、查片机,可用来测量球光镜镜度、散光镜镜度、棱镜镜度以及散光轴线和光学中心点等,是眼镜片冷加工中必不可少的检测仪器。
- The circular symmetric point and the apalanatic point of spherical lens have one same expression,however the two kinds conjugate point are belong to difference category. 圆周的对称点与球透镜的齐明点虽然有一个相同的表达式,但这两类不同范畴的共轭点有着内在的差异,分析这种差异,有利于更好地理解它们。
- At first, the particle is considered as a highly aberrated spherical lens, so that its focal length is gained, and then the equivalent thin lens is found under the condition of the equal focal length and equal light distance. 首先将颗粒作为高象差的球形透镜求出其焦距,再由等焦距和等光程条件找出与球形透镜等价的薄透镜。
