 Press Releases

  • Larger field of view than traditional 2D scanners simplifies the processing of larger parts
     

    Minimal spot distortion over the entire field of view minimizes processing variation for the highest quality laser-processed parts
     

    Air and water cooling options provide thermal stability and improve long-term accuracy
     

    Broad selection of mirror surface treatments support a variety of laser wavelengths
     

    Aerotech’s AGV-SPO single pivot-point galvanometer scanner enables a larger field of view and reduced spot distortion for critical laser micromachining applications. A unique optical design effectively controls the beam entrance pupil to be coincident for the X and Y scanner motion, increasing the effective numerical aperture of the scanner system. This design directly enables a larger field of view for a given focal length and reduces spot distortion over the entire working area. These advantages allow the AGV-SPO to process larger parts faster and with greater consistency.

    The AGV-SPO is available with a selection of optical coatings and focusing optics to support a variety of commonly-used laser wavelengths and focal lengths. Customized optics and optical mounting features are available upon request. The AGV-SPO can be configured with active cooling features such as air-cooled mirrors, water-cooled motors, or both to preserve working-plane accuracy in the presence of thermal disturbances caused by the laser and aggressive motion profiles.

    The AGV-SPO utilizes Aerotech’s advanced motion and Position Synchronized Output (PSO) capabilities. Contouring functions such as Acceleration Limiting can be used to automatically reduce speeds in tight corners or small radii to minimize overshoot. The laser can be triggered based on the position feedback of the mirrors with PSO to ensure consistent spot overlap as the scanner changes speed. Aerotech’s Infinite Field of View (IFOV) function seamlessly combines servo and scanner motion to extend the marking capability of the scanner across the entire travel range of the servo stages. This eliminates stitching errors that can occur in a more traditional move-expose-repeat process.
  • Closed-loop, two-axis servo drive for Aerotech’s AGV series scanners

    Infinite Field of View (IFOV) seamlessly combines AGV and servo motion to expand the scanner work area

    “Zero-tracking error” eliminates speed-related part distortion such as necking on circles and rounding of corners

    Position-based laser firing (PSO) with windowing maintains consistent spot spacing over a wide range of operating speeds

    Fiber-optic interface

    Aerotech’s GL4 scanner controller is optimized for Aerotech’s family of AGV scanners to provide industry leading settling times, long-term thermal stability, and micron-level tracking accuracy due to advanced features such as full state feed-forward, 192 kHz servo rates, and look-ahead-based velocity control. The GL4 uses advanced interpolation electronics to provide up to 26-bits of effective resolution while onboard real-time 2D calibration ensures accurate beam placement over the entire field of view.

    The ability to accurately place a laser spot as a function of X/Y axis position is a key feature of Aerotech’s linear positioning tables for laser processing applications. With the release of the GL4, this functionality is now available for scanner applications. The ability to accurately trigger the laser as a function of position removes the need to program mark, jump, and polygon delays, resulting in reduced programming complexity. By using the Position Synchronized Output functionality, scanner-based processes can now be programmed in the same fashion as traditional X/Y stage-based applications.

    Most competitive scanners have the power devices integrated directly into the head, along with the galvos and feedback devices. These power devices inject thermal energy into the scanner head causing drift in the feedback positions and changing offsets between the mirrors, which reduce marking accuracy. Some systems use PWM power stages to minimize heat input. However, this approach results in reduced tracking accuracy due to nonlinear effects when the galvo motors and control currents reverse polarity. By moving the power stage out of the head, it is possible to use higher performing transistors to drive the galvos and the heat source is effectively removed from the scanner resulting in improved system accuracy.
