Line Confocal Imaging (LCI)
• Non-contact optical measurement method
• High-speed, high-resolution 3D imaging for• Dimensions• Shapes• Profiles• Textures• Flatness• Roughness• Thickness• Air gaps• Defects, etc.
• Unique, globally patented
Line Confocal Sensors – Key Specifications
• 3D points per line 2048
• Z (height) resolution 100 – 980 nm (0.0039 – 0.0386 mil)
• Lateral resolution 2.2 – 36 µm (0.0866 – 1.4173 mil)
• Z (height) range 1.0 – 5.5 mm (0.04 – 0.22”)
• Measurement line length 4.50 – 16.40 mm (0.18 – 0.65”)
• Measurement rate 300 – 4000 lines/second
• Data acquisition rate 0.6 – 8.2 million 3D points per second
Line Confocal Imaging – Strengths
• High speed in-production real-time scanning applications
• Sub-micron resolution
• Line Confocal Imaging works well on• Highly reflective and mirror-like surfaces
• Curved, convex, concave and sloping surfaces
• Transparent and translucent surfaces
• High-contrast (matte-glossy, dark-light) assemblies/surfaces
• Soft and fragile surfaces
• Porous materials
• All surface/object colors
Line Confocal Imaging – Strengths
• Enables measurement of• Thickness of transparent material layers and air gaps
• Microtopography under transparent coatings and layers (tomography)
• Acquires 2048 surface point simultaneously reduced error caused by target vibration
• Native 3-dimensional method
• Produces high-quality raw data
• No speckle effect
• Safe
Confocal Thickness Sensor MCP 100
• Based on infrared reflections
• Dual point operation angle + thickness correction
• Measurement rate:10 kHz
• Thickness range: 0.05 – 5.00 mm (2.0 – 196.9 mil)
• Resolution: 50 nm (0.0020 mil)
• For transparent/translucent materials (polymers, glass, etc.)• Films, sheets• Coatings• Bottles, etc.
• Unique, globally patented
