MarSurf UD 130 Aspheric 2D Asphere measuring station

Checks the contour in the first machining operations

  • Early detection of deviations, thus avoiding costly reworking.
  • Differential profile output in machine-readable format for controlling the machine tool.

Increased flexibility

  • Different types of rotationally symmetrical aspheres can be measured with one measuring system. No additional investment required.
  • Measuring range up to 130 mm
  • High measuring speed and dynamics (up to 5 mm/s for large lenses / up to 0.1 mm/s for microlenses)
  • Fully positionable stylus tip.

Innovative LP D probe arm

  • Improved probe system dynamics by increased rigidity and attenuation as well as a lower moment of inertia:
    – optimized overall design of the probe system
    – innovative choice of materials
  • Probe arm with integrated chip for:
    – detecting and identifying the probe arm,
    – checking that the probe arm is inserted correctly,
    – providing information from probe arm.

Your results will be right

  • The high-precision MarSurf UD 130 is the basis for the accurate measurement of your workpieces. The vertical resolution of 2 nm and form deviations of < 300 nm guarantee the exact reproduction of your asphere.
  • Probe arm change with no need to recalibrate.
  • Lenses with steep sides can be measured.
