High Precision Rotation Mount 5PPH50-1 are ideal for positioning rotation sensitive optics such as polarizers or waveplates. The most common requirement for polarizers is to rotate them about their optical axis. Mounts accept optics of 1" in diameter. Optics are placed inside central aperture, where it is securely held in place by a threaded retaining ring. The position is indicated on 360° angular scale with gradation of 2°. Once mount is fixed in desired position it can be fine ajusted within 5° range with 1 arcmin accuracy. Micrometer screw 9S35 is used, can be optionally replaced with 9SH147 fine hex adjustment screw. The base and side of the polarizer holder has M6 threaded holes for mounting on posts or bases. Surface around mounting holes is flattened so the mount stays rigid once fixed on a mounting post or any other flat base. 5PPH50-1 has a removable rod to rotate the platform by any of its 4 holes.
