DataRay's Polarization Preserving Beam Sampler (PPBS) uses a dual wedge design to sample a small percentage of a beam’s power for laser beam profiling applications.

2022年10月31日 · 通过在ND衰减片或光斑分析仪前面添加光束采样器（PPBS）并且采用光陷阱将废弃的光束吸收，能够避免高功率的光束将仪器损坏。 光束轮廓仪采样器（PPBS）的使用原理. 光束采样器由一对玻璃窗组成，每个玻璃窗都会传输大部分输入光束的能量并将其丢弃或用光陷阱进行吸收，并在每个窗口表面反射一小部分输入光束能量从输出窗口出射以进行测量。 每个窗口发生两次反射——每个表面一次，这就导致会有 4 束光束从PPBS的输出窗口出射，但是由于窗 …

The PPBS samples the reflections from two orthogonal wedge windows to safely reduce the power of high intensity light while preserving the original polarization of the input beam and eliminating the effects of multiple reflections from each air-glass interface. PPBS is a components in laser beam profiler systems.

Polarization Preserving Beam Sampler (PPBS) 是一种用于激光束轮廓测量的光学元件，采用双楔形设计，通过两个正交楔形窗口的反射来采样光束的少量功率。 它能够安全地减少高强度光的功率，同时保持输入光束的原始偏振，并消除每个空气-玻璃界面多次反射的影响。

保偏光取样器（ppbs）可用于激光光束质量分析系统，它采用正交双楔设计从高功率激光束中分出一小部分光进行测量。 PPBS采样的同时保留输入光束的偏振和消除每个空气玻璃界面多次反射的影响，这种精确的激光衰减和分光模式，使得激光形貌不会发生任何 ...
