Aerotech AGV-HP High Accuracy Laser Scan Heads

Offers the highest level of accuracy of any laser



With AGV-HP(O), which offers the highest level of accuracy of any laser scanner, you’ll produce consistent parts with smaller, more precise features. The AGV HP(O)’s highly repeatable and thermally stable feedback sensors allow scanners to be calibrated down to single-digit, micron-level accuracy over the field of view.


  • Attains single-digit, micron-level accuracy throughout the field of view
  • Improves thermal stability significantly with optical feedback technology
  • Delivers industry-best resolution of >24 bits when used with an Aerotech controller
  • Includes wide range of apertures and focal lengths
  • Offers many choices of mirror surface treatments for a variety of laser wavelengths
  • Calibrate micron-level accuracy, count on ultimate stability

With the extremely low thermal gain drift performance of the position transducers, complex, high-density laser machining applications that take long periods of time to complete will maintain consistent micron-level feature placement accuracy over the lifetime of the process. Likewise, high-throughput applications will maintain consistent part-to-part quality without having to re-calibrate between parts. For the highest level of thermal stability, the AGV-HP(O) scanners can be equipped with water cooling to stabilize the operating temperature of the device under varying loads, changes in ambient temperature or beam clipping on the input aperture.


Real-Time Process Visibility

The location of the AGV-HP mirrors can be captured and analysed in real time. With direct access to the positions of the scanner the user no longer has to program delay parameters to compensate for lag and tracking errors in the servo system. The process can be optimised prior to marking the part, saving time and reducing material waste. The state of the laser can also be controlled based on in-position and velocity criteria, further reducing programming complexity.


Advanced Programming Features
The AGV-HP utilises all of Aerotech's advanced motion and PSO (Position Synchronized Output) capabilities that have been developed for traditional servo-based laser processing applications. Contouring functions such as Acceleration Limiting can be used to automatically reduce speeds in tight corners or small radii to minimise 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 (IFOVTM) function seamlessly combines servo and scanner motion to extend the marking capability of the scanner across the entire travel of the servo stages, eliminating stitching errors that can occur in a more traditional move-expose-repeat process.


Design Choices
The AGV-HP family is available with 10, 14, 20, and 30mm input apertures and can be equipped with an F-Theta or telecentric lens directly from Aerotech. Users can also acquire the focusing optic directly from a trusted supplier with Aerotech supplying a spacer ring to ensure that back reflections through the optic do not damage the scanner mirrors. Mirror coatings for a wide range of UV, visible, IR and CO2 wavelengths are supported. Coatings optimised for ultra-fast lasers are also available.
