MarSurf CWM 100 3D Surface Measurement
The multi-measurement solution
The MarSurf CWM 100 is a precise optical measuring instrument with sub-nanometer resolution combining a confocal microscope with a white light Interferometer.

Key benefits:
  • Highest precision with sub-nanometer resolution
  • Universal suitability for technical, optical and reflective surfaces. Also for surfaces of printed circuit boards and semiconductor products as well as biological tissues
  • 2D surface analysis and measuring evaluations
  • Topographic 3D surface analysis and measuring evaluations
  • Intelligent measuring strategies - fast measurements – short measuring times
  • Microscope image field sizes, easily expandable by fully automatic stitching
  • Automatic table or object positioning: 100 mm x 100 mm, longer distances on request
  • A wide range of lenses allows for an ideal adaptation to the measurement object
  • Solid construction with granite base plate and granite column for the best possible vibration damping
  • Technical data
  • Applications
  • Accessories
  • Shipment
