TWIP optical 3D roughness measuring device CONSIGNO SR confocal linear drive

Application

Optical 3D measuring instrument for non-contact recording of surface roughness. Measuring principle based on confocal microscopy with micro-lens technology for high light efficiency.

Execution

• Digital camera with 1280x1024 pixels and 60 frames per second
• 20x lens with long working distance
• Calibration object for the reference plane
• Integrated laser diode (450 nm)
• Linear axis with 25 mm travelling distance for standard-compliant recording of the measurement path
• Step motor drive (scan path approx. 20 mm) for the Z axis
• Incremental linear measuring system with glass scale (5 nm resolution)
• Software for performing roughness measurement and evaluation
• PC for control
