An optic axis of a crystal is a direction in which a ray of transmitted light suffers no birefringence (double refraction). An optic axis is a direction rather than a single line: all rays that are parallel …

Optical axis (coincides with red ray) and rays symmetrical to optical axis (pair of blue and pair of green rays) propagating through different lenses. An optical axis is an imaginary line that …

通过晶体的光波方向可由波矢量 k 表示，这相当于通常所说的光轴 (Optical Axis)或传播轴方向。 如果光为线偏振且偏振方向垂直于 传播光轴 和 晶体光轴 所在的平面，即 k 和 ne 所在的平 …

光束 (光柱)的 中心线，或 光学系统 的 对称轴。 光束绕此轴转动，不应有任何光学特性的变化。 通过镜头中心的 线。 晶体根据其光学特性可以分为 均质体 和 非均质体 当光线经过非均质体 …

2024年9月22日 · 光轴 （英语： optical axis）是 光学 系统（如照相机 镜头 、 显微镜 、 望远镜 、 眼球 屈光系统）中一条假想的线，定义（在一次近似下）光学系统如何传导光线，此假想 …

Optical axis, the straight line passing through the geometrical centre of a lens and joining the two centres of curvature of its surfaces. Sometimes the optical axis of a lens is called its principal …

The optic axis is defined by the propagation direction at which the wave feels the same refractive index without dependence on the polarization direction. From: Integrated Nanophotonic …

晶体光轴（optical axis of crystal），光在 各向异性 的 晶体 中传播不产生双折射现象的方向。 各向异性 晶体内的一个方向，沿着此方向不产生双折射，形成单一折射光。 即光线在 各向异性 …

optic axis is the axis that has a different index of refraction also called c or crystallographic axis fast axis: axis with smallest index of refraction ray of light going through uniaxial crystal is …

Uniaxial minerals are a class of anisotropic minerals that include all minerals that crystallize in the tetragonal and hexagonal crystal systems. They are called uniaxial because they have a single …
