MarSurf LD 130 / 260 Aspheric 2D and 3D

Asphere Measuring Station

DESCRIPTION

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

Measurement of steep aspheres with stitching, step 1:
