Product Description:
The Rotary Actuators have taken the technology of the rectangular linear actuator and bent therm to provide a high resolution limited angle positioning system.
The Rotary Actuators are typically utilized as mirror position Actuators for laser technologies,rotary valve and damping Actuators, rotary positioning systems and flight control Actuators, Rotary Actuators markets include semiconductor,automotive,industrial and aerospace industries.
Rotary voice coil motors are used in laser focusing:
Lens Focusing:By installing a lens on the rotary voice coil motor, the laser beam is focused to a small spot. This method is simple and easy to use, but the focusing accuracy is low.
Mirror focusing: Using a mirror to reflect the laser beam to a small point. This method achieves higher focusing accuracy, but requires precise adjustment of the position and angle of the reflector.
Dynamic Focusing:By controlling the movement of the rotary voice coil motor, the laser beam is focused at different positions. This method enables focusing on objects at different depths and is suitable for applications such as three-dimensional processing.
Adaptive Focusing:Sensors are used to detect the focusing of the laser beam and the motion of the voice coil motor is adjusted through a feedback control system to achieve automatic focusing. This method improves focusing accuracy and stability, but the system complexity is high.
