The PRM1GL10 high precision rotation mounts combine easy-to-use manual rotation with high precision, backlash-free micrometer adjustment. While the knurled dial is in the 'unlocked' position, the dial rotates smoothly and it can be coarsely adjusted using the laser engraved graduation marks. With the mount in the 'locked' position, the dial is adjusted manually via a fine drive adjuster.

The PRM1GL10 bundles our PRM1 rotation mount featured above with our SM1PM10 polarizing prism mount. The SM1PM10, which features external SM1 threading, is directly compatible with the PRM1. Its rotating cover allows the user to block the two side ports when they are not required. The PRM1GL10 provides 360° of high precision rotation for our GL10 and GT10 polarizing prisms (sold separately).

The PRM1GL10 is also compatible with our 30mm cage system. The unit can be mounted to a cage system using ER cage assembly rods attached to the four front face taps.
