Optimal Engineering Systems Inc. (OES) has released the YP200-30 series of dual-axis, yaw-pitch stages. This series of yaw-pitch stages features a high precision rotary stage (yaw-axis) capable of clockwise and counterclockwise rotation and a high precision goniometer with ±30° of travel. The pitch axis table measures 160mm by 160mm with a precision pattern of threaded holes for tooling and fixtures. The integration of high precision rotary and goniometer stages creates platforms for the precise measurement of curves and angles. The YP200-30 series dual-axis yaw-pitch stages have easily accessible mounting holes for easy integration into new and existing applications. The yaw axis has a home switch for initialization and the pitch axis has two end-of-travel limit switches.
The YP200-30-01 (pictured) is driven by two-phase stepper motors with knobs for manual adjustments, whereas the YP200-30-04 stage has quadrature incremental optical encoders for position verification. The YP200-30-02 is driven by three-phase brushless servo motors with quadrature incremental optical encoders and the YP200-30-03 is driven by DC brushed servo motors with quadrature incremental optical encoders. These servo motor driven stages feature: better repeatability and positional accuracy, and higher travel speeds typical of a closed loop servo motor system. The repeatability with a 10 micro-steps-per-step motor driver of the yaw and pitch axes is ± 0.01°, positional accuracy is 0.05° and resolution 0.001° (3.6 arcsec). The stages are black anodized aluminum, with a high load capacity of 25.0kg and the rotation center height is 136mm.
These stages require a multi-axis motion controller that can be ordered as a complete plug-and-play system with RS-232, USB, joystick, and keypad control.
