可迭加式棱镜前表面光束取样器 通过单/双棱镜前表面衰减器实现激光光束衰减
棱镜前表面光束取样器（PFSA）是封装了UV级熔融石英直角棱镜的C型接口设备，在高功率/能量光束轮廓分析应用中用于前表面反射取样。在45°标称入射条件下的反射率取决于偏振光和波长，532nm s-偏振光反射率为8.27%，p-偏振光反射率为0.68%。

功能
Single and Dual Prism Front-Surface Beam Samplers
The Front-Surface Beam Sampler is available as either a single prism (PFSA) or dual orthogonal prism (DPFSA) unit. Reflection of the prism at the nominal incidence of 45° is polarization and wavelength dependent, with 532 nm s-polarization reflected at 8.27%, and p-polarization at 0.68% for PFSA. The DPFSA configuration results in polarization independent reflection of 0.057% at 532 nm.
| Reflection at λ (nm) | P- Polarization | S- Polarization |
|---|---|---|
| 248.3 | 0.88% | 9.40% |
| 351.1 | 0.75% | 8.65% |
| 532 | 0.68% | 8.27% |
| 1064 | 0.64% | 8.01% |
Other filters and attenuators can be attached using the C-mount female threads at the input end. The use of a right-angle prism to sample the incident beam guarantees that any scattered secondary beams do not interfere with the measurement.
