The 05BC16PC.12 Laser Line Polarizing Cube Beamsplitter provides efficient narrowband polarization for higher power lasers. This polarizer consists of a pair of precision 1/2 inch (12.7 mm) right-angle prisms carefully cemented together to minimize wavefront distortion. The hypotenuse of one of the prisms is coated with a multilayer dielectric polarizing beamsplitter coating optimized for the 670 nm laser line. The four faces are antireflection coated with a multilayer dielectric coating to minimize surface reflection losses. An unpolarized beam is split into two orthogonal, linearly polarized components. P-polarized light is transmitted, while s-polarized light is reflected, both with negligible absorption. The extinction ratio is better than 1000:1. This cube is recommended for use in pulsed laser systems and for purifying polarization in multimode, high-power lasers.

05 bc16pc。激光线偏振立方体波束分离器为高功率激光器提供了有效的窄带偏振。该偏振器由一对精确的1/2英寸(12.7 mm)直角棱镜组成，它们被小心地粘合在一起，以减少波前畸变。其中一个棱镜的斜边涂敷了针对670nm激光线优化的多层介质极化波束分离器涂层。四个表面都涂有一层多层介质涂层，以减少表面反射损失。非偏振光束被分成两个正交的线性偏振分量。p偏振光被发射，s偏振光被反射，两者的吸收都可以忽略。消光比大于1000:1。这个立方体被推荐用于脉冲激光系统和净化偏振在多模式，大功率激光器。
