1 Nmark AGV-HP High Accuracy, Thermally Stable Galvo Scanner Highest accuracy scanner available attains single-digit, micron-level accuracy over the field of view Optical feedback technology significantly improves thermal stability Industry-best resolution of >24 bits when used with Aerotech s Nmark CLS controller Wide range of apertures and focal lengths Many choices of mirror surface treatments for a variety of laser wavelengths The Ultimate in Accuracy and Stability The highly repeatable and thermally stable feedback sensors used on the AGV-HP scanner systems can be calibrated down to single-digit, micron-level accuracy over the field of view (see figure below). 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 scanners can be equipped with water cooling to stabilize the operating AGV-HP galvo scanner offers micron-level accuracy over the field of view. 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 analyzed 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 optimized prior to marking the part, saving time and reducing material waste. The state of the laser can also be controlled based on inposition and velocity criteria, further reducing programming complexity. Advanced Programming Features The AGV-HP utilizes 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 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 TM ) 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. Nmark AGV-HP provides industry-best micron-level 2D accuracy over the entire field of view. Design Choices The AGV-HP family is available with 10,, 20, and 30 mm 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 optimized for ultra-fast lasers are also available. 1

In traditional scanning systems the tracking error is used to set the delays between laser pulses in order to compensate for the lag between command and response. The Nmark CLS features Position Synchronized Output (PSO) capability that permits laser pulse commands to be tied directly to the position feedback of the galvo motors, thus providing laser scanner control with 0 (or near 0) tracking error. 8. All angles are optical unless otherwise noted. 9. All specifications are per axis unless otherwise noted.
