Two-dimensional Precision Turntable

  • 格物光学-二维精密转台.png



    The GS series two-dimensional precision turntable of Gewu Optics adopts the design concept of large-size hollow and orthogonality, which can achieve high-precision and high stiffness 360 ° unrestricted rotational motion of pitch and vertical rotation axes. It can be widely used in fields such as laser guidance, LiDAR, and airborne target tracking, especially suitable for optoelectronic sensors and forward-looking infrared testing, gyroscope angle testing, and inertial unit acceleration testing.
