GM-12 Gimbal

Newmark's high precision 12" gimbal system is designed for general purpose pointing, scanning and tracking applications for large optics, antennae and other sensors.

Our large gimbal system is equipped with High Performance rotary stages and offer excellent stiffness and load capacity making them suitable for a wide variety of applications. Depending on the positioning requirements, the gimbal can be equipped with shaft mounted rotary encoders or direct-read high accuracy optical encoders. And since we can also supply the control electronics, we can guarantee your system's positioning performance.
