GM-12E Gimbal

Newmark's high precision 12" gimbal system is designed for high accuracy 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. The GM-12E is equipped with direct-read high accuracy optical encoders mounted to the rotating output spindle. This effectively eliminates all positional errors associated with the drive train. And since we can also supply the control electronics, we can guarantee your system's positioning performance.
