Free-Space Rotation Mounts

Free-Space Rotation Mount is designed for mounting anisotropic optical components (such as polarization optics). It features a central SM-series internal threaded mounting hole and comes with an SM-series retaining ring for securing optical components. The rotation mount allows 360° rotation of the internal optical component, with graduation marks at 2° intervals and numerical indicators every 20°. A locking screw on the side can secure the rotating body. The base includes an M4 threaded hole for connection to optical posts.
