Optical profilometer Optimap3

surface flatnesscontoursurface roughness

Overview
Optimap3 is a portable full-field surface inspection instrument that maps surface topography and converts it into objective surface data for production control. It captures high-resolution altitude and curvature maps of coated and uncoated substrates and highlights defects and texture variations across large areas quickly.

Key capabilities

• Full-field surface mapping and measurement.
• Characterisation of texture and common surface defects including orange peel, inclusions, dents, scratches and sagging.
• Dual-mode operation for reflective and dull surfaces (Dual-Focus).
• On-screen magnification and interactive cross-section profiling.

Representative surface analysis
Optimap3 objectively quantifies surface quality parameters such as texture, waviness and local defects (orange peel, inclusions, blistering, sagging, pinholes, scratches). The system produces detailed altitude and curvature maps and provides on-screen tools to visualise and measure features.

What the Optimap3 can measure

• Orange peel
• Waviness
• DOI (Distinctness of Image)
• Overspray
• Inclusions
• Blistering
• Sagging
• Waterstains

Measurement method
Phase Measurement Deflectometry (PMD): coded fringe patterns are shown on an internal target and reflections from the surface are recorded by an internal dual-focus camera. Phase-stepped processing in X and Y generates high-resolution surface maps. Two modes (reflective / dull) optimise fringe contrast for different surface reflectivities.

On-screen functionality

• Interactive cross-sectional viewing: place and move cross sections across the map to inspect height and profile changes.
• Magnification slider for zooming into fine features.
• Built-in texture and waviness filters, profile analysis and exportable results.

Applications and surfaces
Suitable for automotive (exterior & interior), plastics and composites, furniture, paints & coatings, displays, aerospace and yacht coatings. Works on substrates such as steel, aluminium, plastics, e-coat, primer, clearcoat, vinyl wrap and chrome parts.

Included accessories

• Verification tile
• USB key
• Instruction manual
• Optimap Reader software
• Removable measurement base

Optional accessories

• Non-contact base for measuring wet paint
• Custom jigs and fixtures

Software
Optimap Reader software provides tools for identification, classification and quantification of surface defects (pinholes, inclusions, scratches). Offline analysis and export of maps and CSV results are supported.

Instrument verification
No calibration is required. Periodic verification (recommended about every 3 months) uses the supplied reference tile: a verification measurement is compared to tile values to confirm performance.
