Rhopoint Optimap3 PSD

Why Optimap3 PSD?

• Full-field surface mapping in under 10 seconds — cover a 65 x 54 mm area in one measurement. 

• Unmatched resolution — lateral resolution < 37 µm reveals surface defects invisible to the naked eye. 

• Dual-mode operation — supports both reflective (mirror/bright) and dull surfaces using different fringe frequencies. 

• Non-contact measurement — safe for wet coatings; uniquely captures “orange peel” on freshly applied paint. 

• On-board, intuitive interface — 10.1″ capacitive touch screen, cross-section analysis, and instant 3D visualization. 

• Portable and robust — battery-powered, harness-mount points, rugged base options, and factory/Lab or on-site use. 

• Industry-ready outputs — Provides data in SI units or industry scales (e.g., “orange peel” units, waviness, DOI).

Key Applications & Industries

Optimap3 PSD excels in sectors where surface appearance and finish matter critically:

• Automotive — Inspect exterior panels, clearcoats, E-coats, vinyl wrap, chrome parts. 

• Plastics & Composites — Analyze molded or curved components for texture, primer or topcoat defects. 

• Furniture & Metal Finishing — Evaluate lacquered, polished or curved surfaces for waviness or inclusions. 

• Paints & Coatings R&D — Measure wet paint finish, study defect formation (blistering, waterstains, sagging).

• Consumer Electronics / High-End Surfaces — For device covers, panels, and premium finishes that demand uniformity. 

How It Works — Measurement Principle

1. Phase-Measurement Deflectometry (PMD):
   Fringe (striped) patterns are projected from an internal screen. The patterns shift in X and Y (phase stepping).

2. Reflection & Capture:
   The surface reflects these patterns. Because of surface texture or defects, the reflected patterns are distorted. An internal dual-focus camera captures these distortions. 

3. Topographic Mapping:
   Built-in software reconstructs surface slope maps from the phase data. From there, it computes curvature (or altitude) maps showing waviness, orange peel, and more. 

4. Dual Surface Modes:

   • Reflective mode (high-frequency fringes) for glossy or shiny surfaces.

   • Dull mode (low-frequency fringes) for matte or low-reflectance surfaces. 

5. Analysis Tools:

   • On-screen cross-sections: touch any point on the 3D map to generate profile plots over X / Y axes. 

   • Magnification slider lets you zoom in on features. 

Measurable Parameters & Defects

Optimap3 PSD can detect and quantify:

• Orange peel (surface “skin” texture) 

• Waviness (low-frequency surface undulations) 

• Distinctness of Image (DOI) — how clearly a reflection appears 

• Overspray — unintended surface material

• Inclusions — foreign particles embedded in the coating or substrate 

• Blistering / Bubbling

• Sagging / runs

• Water stains / spots 

Key Benefits

• Highly Representative Results: One fast full-area measurement gives you objective, quantifiable data that’s more meaningful than subjective visual inspections.

• Defect Detection & Characterization: Identify, map and size defects, waviness or texture variations with 3D mapping.

• Portable & Versatile: Battery powered, lightweight—even usable in the field or on production lines.

• User-Friendly: Touch-screen interface, intuitive operations, fast training.

• Industry Correlation: Measurement parameters correlate with visual appearance standards (e.g., automotive “orange peel” scales) and interferometry.

• Robust Data Handling: Store data locally, analyze offline, export maps or CSV, integrate with SPC systems.

Ideal For

• Quality Control Teams in automotive, coatings and plastics manufacturing

• R&D Laboratories developing new finishes or paint formulations

• Process Engineers optimizing finishing lines to reduce defects and material waste

• Manufacturing Maintenance for periodic inspection of surface appearance on production parts
