IIVINFRARED反光相位延迟器产品介绍及选型
金属切割和其他重要的激光操作对切缝宽度或横截面的任何变化都很敏感。切缝的质量取决于相对于切割方向的偏振方向。
当前的理论表明，只有在切割开始时，聚焦光束才以垂直入射角撞击工件的假设才是正确的。切口形成后，光束会以较大的入射角θ遇到金属。相对于这样的表面，s偏振的光比p偏振的光反射得多，从而导致切割质量的差异。
在光束传输路径中引入四分之一波（90°）反射相位延迟器（RPR），可以通过将线性偏振转换为圆偏振来消除切缝变化。对于任何光束方向，圆偏振都由相等数量的s偏振和p偏振组成，因此所有轴都遇到相同的偏振成分，并且无论切割方向如何，材料都被均匀去除。
调整线偏振光束的方向，使偏振平面与入射平面成45°角，并与法线成45°入射到RPR。反射光束是圆偏振的。
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.
