本文分析推导了透镜的凹面反射成像与凹透镜焦距的关系 ,介绍了利用此关系较方便地测量凹透镜焦距的方法。
5) concave cylindrical lens
凹柱透镜
1.
Then a concave cylindrical lens is designed to obtain one-dimensional uniformized intensity.
推导出激光二极管线阵光束通过透镜系统的光强分布表达式 ,分析了出射光束的传输特性 ,设计一种凹柱透镜的光束变换系统得到一维均匀光强分布。
6) concave mirror
凹透镜
1.
Light beams scatter through refraction of concave mirror, and can not form true image, hence we can not measure the focus of concave mirror directly.
光束经凹透镜折射后发散,不能形成实像,因此不能直接测量凹透镜的焦距。
补充资料：凹透镜
| 凹透镜 concave lens 中央薄边缘厚的透镜。在光疏介质中使用时，能对入射光束起发散作用，故又称发散透镜。又因其焦距为负，又称负透镜。对薄的凹透镜，成像公式、横向放大率公式和符号法则均与凸透镜同（见凸透镜）。 |
