IIVINFRARED反光相位延遲器產品介紹及選型
金屬切割和其他重要的激光操作對切縫寬度或橫截面的任何變化都很敏感。切縫的質量取決于相對于切割方向的偏振方向。
當前的理論表明，只有在切割開始時，聚焦光束才以垂直入射角撞擊工件的假設才是正確的。切口形成后，光束會以較大的入射角θ遇到金屬。相對于這樣的表面，s偏振的光比p偏振的光反射得多，從而導致切割質量的差異。
在光束傳輸路徑中引入四分之一波（90°）反射相位延遲器（RPR），可以通過將線性偏振轉換為圓偏振來消除切縫變化。對于任何光束方向，圓偏振都由相等數量的s偏振和p偏振組成，因此所有軸都遇到相同的偏振成分，并且無論切割方向如何，材料都被均勻去除。
調整線偏振光束的方向，使偏振平面與入射平面成45°角，并與法線成45°入射到RPR。反射光束是圓偏振的。
Metal cutting and other critical laser operations are sensitive to any variation in kerf width or cross-section. The kerf’s quality depends on the polarization orientation relative to the cut direction.
Current theory suggests that the assumption of a focused beam striking the work piece at normal incidence is only true at the cut’s beginning. Once the kerf forms, the beam encounters metal at some large angle of incidence, Θ. Light which is s-polarized with reference to such a surface is reflected much more than light which is p-polarized, leading to the difference in cut quality.
Introducing a quarter-wave (90°) reflective phase retarder(RPR) into the beam delivery path eliminates kerf variations by converting linear polarization to circular polarization. Circular polarization consists of equal amounts of s-polarization and p-polarization for any beam orientation, therefore all axes encounter the same composition of polarization, and material is removed uniformly regardless of cut direction.
A linearly polarized beam is oriented so that the plane of polarization is 45° to the plane of incidence and strikes the RPR at 45° to the normal. The reflected beam is circularly polarized.
