However, such a divergent beam can be transformed into a collimated beam by means of a lens.
然而,这种散射的光束可以通过镜头的帮助被转化成平行光束。
The theoretical expressions of the collimated beam of a DHCL are derived by transmission theory, and the numerical results are also given.
基于光线传输理论导出该结构柱透镜准直激光光束的基本公式并给出数值模拟的结果。
If a monocentric system existed for which an incident collimated beam emerged as exactly collimated, then the system would give geometrically perfect imaging of any point in space.
当入射光束与出射光束平行时,单色同心光学系统空间任一点成几何理想像。
The optical system includes at least one lens element, which outputs the light in a collimated beam on the oscillating reflector regardless of an orientation of the oscillating reflector.
该光学系统包括至少一个透镜元件,其与振荡反射器的定向无关地以准直光束的形式将光输出在振荡反射器上。
Another important application of diffraction theory is the study of the far field divergence Angle of a collimated light beam.
衍射理论的另一个重要应用就是研究准直光束的远场发散角。
准直光束(Collimated Beam)指光线或粒子束在传播过程中保持高度平行状态的光学现象,其发散角极小(通常小于1毫弧度)。这种特性使得光束在长距离传输中仍能维持能量集中性,避免因扩散导致的光斑变形或能量损失。
核心原理基于几何光学理论,通过透镜组、反射镜或光纤等准直器对原始发散光束进行校正,使光线传播方向趋于一致。例如激光器输出的光束需经过准直处理才能应用于精密加工。美国国家标准与技术研究院(NIST)的实验数据显示,准直光束的平行度误差可控制在0.01°以内,满足高精度光学系统的需求。

“Collimated beam”是光学和物理学中的专业术语,指经过校准后形成的平行光束,其光线或粒子束在传播过程中发散度极低。以下是详细解释:
普通光源(如灯泡)发出的光呈发散状,而准直束通过光学元件校准后,能在特定范围内保持平行,例如Holo/Or的准直平顶光束整形器可在20-30cm距离内维持准直性。
