  • Machine Positioning Uncertainty with Laser Interferometer Feedback
    The purpose of this discussion is to explain the major contributors to machine positioning uncertainty in systems with laser interferometer feedback near the work point. We will use an example to quantify these uncertainties in a real implementation of a laser-feedback-driven machine.
  • Synchronizing Position Synchronized Output (PSO) with Mode-Locked Lasers
    Many lasers are limited to firing pulses based on an internal clock source and cannot be asynchronously triggered from an external. signal such as from Aerotech's Position Synchronized Output (PSO) feature. One approach to working with this laser type is to. set the pulse width of the PSO output
  • Measuring the Smallest Resolution of a Positioning Stage
    The noise measured by the external metrology (laser) contains the sum of all mechanical and electrical sources - the amplifier noise, the servo noise, the sensor noise, the vibrational noise from ground and, acoustic disturbances etc. Can the data be used to predict the smallest step size
  • 3-DOF Precision Positioning Stages Supporting Laser Assisted Wafer Slicing
    Granite-based XY-Theta positioning stages with direct-drive motors and air bearings for ultra-high precision 3-axis motion
  • Laser Triangulation Sensors
    Offering extreme resolution and high measuring rates, laser triangulation sensors accurately measure displacement, position and vibrations on an engine manifold, powertrain or car body.
  • Tackling Laser Visibility
    Our customers often ask us if a laser spot can be seen in their application. While such information can be a critical factor in anything from alignment to targeting applications, the answer to this question can be difficult because it may vary from application to application. It is important
  • Perfectly Positioned: A Laser Shows the Way
    Every surgical operation has inherent risks. New technologies help to minimize these risks, for example with high-precision 3D navigation for computer tomography.
  • Artificial Stars Created with Laser Technology
    Southern Observatory (ESO). The so-called "Optical Tube Assemblies" are complex projection systems for generating artificial stars. A high-precision drive system with two brushless maxon flat motors, planetary gearhead with spindle and encoder ensures accurate positioning of the laser.
