Beam Manipulation in 5 Degrees of Freedom

Aerotech’s AGV5D five-axis laser micromachining precession scanner manipulates a laser beam in five degrees of freedom (DOF):
  • Spot placement within the field of view (2-DOF)
  • Spot focus depth (1-DOF)
  • Precession angle (2-DOF)
AGV5D produces extremely precise holes, slots and user-defined geometries, while maintaining exact control of the cross section.

One Controller for All Motion

Through coordination with other axes of motion using an Aerotech controller, AGV5D offers the unique capability to generate features larger than its field of view while maintaining the highest processing quality. Regardless of whether the motion platform is comprised of servo-motor or stepper-motor stages, piezoelectric nanopositioners, or hexapods, Aerotech is the only supplier that coordinates the precession scanner with the other motion axes, resulting in the greatest laser-processing precision possible.

A G-code-based programming interface gives you the ability to take control and forge your own trajectory. Alternatively, defined functions with parametric features and geometries are available for programming simplicity. User-accessible diagnostic tools accelerate process development and optimization.

Simple and Flexible Integration

AGV5D is the most flexible multi-axis laser micromachining solution available. Mounting interfaces on the front and rear faces of the housing, along with a multidirectional beam input, simplify delivery of the input beam. Additional kinematic mounting features on the underside of the housing allow for repeatable dismounting and remounting of the AGV5D, thus minimizing the need for realignment of the input beam. Optional beam alignment modules provide a simple mechanism by which users can set and adjust the input beam alignment and the polarization.

AGV5D also offers great flexibility to users in that it is easy to integrate with a diverse range of commercially available femtosecond lasers. This is made possible through adjustable software parameters, allowing users to compensate for laser properties such as beam divergence, diameter and quality, which often vary among laser sources. With some relatively quick and simple adjustments, users can set up the AGV5D with the laser that best suits their process requirements, and can easily swap out one laser for another.

Optimized for Industrial Use

Like all Aerotech products, AGV5D is designed for long-term durability in production environments. Water- and air-cooling mechanisms regulate temperature gradients within the AGV5D, thereby mitigating thermal drift errors. The housing is sealed and includes an air purge to help keep the optical components free from contamination, greatly reducing the risk of damage.

Notes:
1. Consult factory for other wavelengths.
2. Valid for input beam diameters of 2 mm (1/e2) and larger. Contact factory if input beam diameter is less than 2 mm.
3. To avoid damage to the optics, the minimum laser pulse length should not be less than 250 fs. For optimal focused spot quality, a minimum pulse length of 400 fs is recommended.
4. Diameter is represented as 1/e2 and assumes an input beam quality of M2=1.2. Values shown assume a 2.3 mm (1/e2) input beam diameter.
5. Entrance beam diameters exceeding the maximum value can result in a reduction in the field of view and/or maximum precession angle.
6. Requires the -AM2 alignment module option, or alternatively, external customer-supplied polarizing optics.
7. Maximum travels are listed for the specified input beam diameter and are mutually exclusive. Consult factory for detailed working volume sizing.
8. Working distances greater than 3.25 mm from the nozzle will restrict the maximum precession angle.
9. Precession frequency is dependent on angle of incidence and feature diameter.
10. If nitrogen is used, it must be 99.99% pure and filtered to 0.25 µm. If compressed air is used, it must be filtered to 0.25 µm, dry to 0º F dew point and oil free.
11. Water- and air-cooling inputs are standard on all AGV5D models. The use of these cooling features is recommended, but is not strictly required in all use cases.
