The RM25A Polarizer Rotation Mount allows 1 in. (25.4 mm) diameter linear polarizers, wave plates, Glan-laser calcite polarizers, and polarizing cube beamsplitters to be continuously rotated 360 °. The extra deep mounting barrel holds polarizers up to 0.5-inch thick. A graduated scale marked in 2 ° increments indicates angular position. Rotation can be locked to prevent accidental adjustment and reduce drift. The 1-inch diameter rear flange on RM25A can be mounted to U100-A ULTIMA® optical mounts for precision tip/tilt and rotation. Three tapped holes per side permit secure mounting in industrial OEM optical systems. A 1/2-in diameter polarizer or waveplate can be mounted to the RM25A rotator mount using the PRA-05 Adaptor, which screws into the rotator's 1.063-20 thread. The PRA-05 Adaptor included a retaining ring. Note: RM25A is not compatible with Glan-Thompson Polarizers.

RM25A偏振器旋转安装允许1英寸。(25.4毫米)直径线性偏振波板、立方体Glan-laser方解石偏振器和偏振分光膜不断旋转360°。特别深的安装筒可容纳0.5英寸厚的偏振器。在2°刻度尺明显增量表示角的位置。旋转可锁定，防止意外调整，减少漂移。1英寸直径后可以安装法兰在RM25A U100-A天涯®光学精密技巧/倾斜和旋转支架。在工业OEM光学系统中，每边三个抽头孔允许安全安装。可以使用PRA-05适配器将直径1/2英寸的偏光器或波板安装到RM25A旋转器上，该适配器将螺钉固定在旋转器的1.063-20螺纹上。PRA-05适配器包括一个固定环。注:RM25A与格兰-汤普森偏振器不兼容。
