The Sin216R series are ultra-precision computer controlled angular stages developed for accurate positioning applications. Sine-bar mechanism is employed in this device for higher resolution angular positioning. A precision linear translation stage with a high resolution optical encoder is used in the mechanism for achieving angular tilt of the sine bar. The absolute encoder allows instant initialization at the time of power up and eliminates the need for a home cycle. The stepper motor turns the drive lead screw which moves the drive block which in turn pushes the sine bar to rotate the platform, providing stable and excellent performances in angular positioning.
The principle of sine drive mechanism is shown schematically in Fig. When a lever of length L is rotated through an angle θ about one end, the other end moves through a distance X = L Sin θ perpendicular to the initial position of the lever. Standard metric M4 mounting holes patterns are provided on the top plate of these stages. Top plate can be used to position manually large optical and other components through with accuracy of 1°. Custom mounting patterns can be provided for easy integration with other systems / components.
The Sin216R series stages are perfect for rotary positioner testing, laser pointing, optical calibration systems and metrology systems. Other specific applications include optical encoder accuracy testing, missile seeker testing, photonic component alignment and precision wafer inspection.
