MarSurf LD 130 / LD 260. A step into a new dimension
MarSurf LD 130 / 260 Aspheric is a high-precision 2D / 3D surface measuring station for characterizing contour and roughness on optical components. MarWin is the software used for operation and analysis.
Checks the topography 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.
  • Large measuring range up to 260 mm (up to 400 mm with the stitching option)
  • Maximum measuring speed and dynamics (up to 10 mm/s for large lenses / up to 0.02 mm/s for microlenses)
  • Fully positionable stylus tip.

Bionic-style LP D probe arm

Improved probe system dynamics thanks to 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 LD 130 / 260 is the basis for the accurate measurement of your workpieces. The vertical resolution of 0.8 nm and form deviations of < 100 nm guarantee the exact reproduction of your asphere.
  • Probe arm change with no need to recalibrate.
  • Lenses with steep sides can be measured.
