Because the fast mirror is special, and is one of the core components of the optical precision tracking control system, its application scene is also quite special, it is mainly used in long-distance laser communication, adaptive optics, space telescope system and other optical systems. 

     So what is the role of fast mirrors in these systems? It is reported that the introduction of fast mirror in these systems can bring a series of advantages. The disturbance on the moving carrier in the system is of wide frequency band, and the traditional control method has limited anti-disturbance ability, which can not meet the high demand of stability control, the disturbance of the pedestal on the moving platform will be transmitted directly to the mirror, which will reduce the stable tracking accuracy of the deflection beam and destroy the system performance greatly. As for the fast mirror, voice coil motor has been used in practical cases, voice coil fast mirror through the mirror's two-axis fast swing vibration to achieve the adjustment of the light path, to compensate the vibration on the light path, or control the light path to produce the desired direction. The voice coil mirror is driven by a specially designed precision voice coil motor with high output force, fast response and high control accuracy, it reduces the mass/inertia, reduces the volume, and has excellent dynamic characteristics. The rotating shaft configuration optimization technology is adopted to make the fast mirror have good control accuracy and closed-loop bandwidth. 

      Kunshan Tongmao Electronics Co. , Ltd. is a high-tech enterprise with more than 10 years of sales experience in voice coil motor r & D, can provide 5000N, 300mm stroke linear voice coil motor, can provide 50n peak.
