IntelLiDrives Inc.Request Info
Intellidrives Inc.’s RTHM-174 micro rotation stages are designed to rotate optical components and small tooling in confined spaces, such as laser cavities, disk texturing machines, and manufacturing areas for fiber optical components and semiconductor devices. The stages’ lightweight, low-profile design incorporates an anodized aluminum body with preloaded ball bearings. This proprietary bearing design provides smooth rotation with minimal wobble. A precision ground worm gear produces consistent driving torque to the rotor and eliminates variations in the motor current. The stages produce an angular resolution up to 0.2 arcsec, which may be achieved with either DC servo or stepper motor controls. They are equipped with a reference home sensor, can run in continuous rotation mode, and can be mounted horizontally or vertically. They feature a small footprint of only 40 mm and are 25 mm high, with a center aperture of 11 mm.

An opening or hole through which radiation or matter may pass.
1. The sector of the Earth's surface registered upon a remote sensing device in a satellite. 2. The amount of space occupied by a component on the surface upon which it is mounted. 3. The space on an optical component occupied by a light beam.
1. In optics, the ability of a lens system to reproduce the points, lines and surfaces in an object as separate entities in the image. 2. The minimum adjustment increment effectively achievable by a positioning mechanism. 3. In image processing, the accuracy with which brightness, spatial parameters and frame rate are divided into discrete levels.
A calculated measure of the ability of an incident force to cause an object to spin. The spin speed of any given object is a direct function of the duration of the torque application.
In micropositioning systems, motion (most frequently undesired) about the Z-axis.
