What is Optical Scanning and How Does It Work?
Optical scanners using structured light technology create a three-dimensional model of a surface by projecting light patterns onto the object. With this method:
- Reverse engineering: CAD model creation from physical parts
- Geometric measurement analysis
- Quality control reporting can be performed with ease
What Are the Advantages?
- Non-contact measurement: Fragile, flexible, or specially coated parts can be measured without damage
- High resolution: ZEISS Comet L3D allows capturing details up to 10 microns
- Fast data collection: Saves time for mass production and process control
- Ideal solution for prototype analysis: Provides fast and precise results during the evaluation of test phase parts
- Effective for parts not measurable by CMM: Optical scanning is the safest alternative for flexible or irregular surfaces
- True 3D analysis: Deformation, surface defects, and geometric deviations can be visualized digitally
In Which Industries Is It Used?
- Plastic part manufacturers and mold-making industry
- Electronic device components
- Automotive and white goods production
- Thin-walled, soft, or complex-shaped parts
- Parts not suitable for mechanical contact measurement

Frequently Asked Questions (FAQ)
- What is the difference between optical scanning and CMM measurement?
CMM (Coordinate Measuring Machine) uses a contact method and typically collects data from fewer points. Optical scanning is non-contact and captures the entire surface with high-density data. It is especially suitable for flexible, delicate, or complex surfaces.
- What materials can be scanned using optical scanning?
It can be applied to a wide range of materials such as plastic, metal, ceramic, and composite. Surface preparation (e.g., spray) may be needed for shiny or transparent surfaces. Ideal for materials at risk of deformation during measurement.
- What size parts can you scan?
With our ZEISS Comet L3D device, parts between 10 mm and 500 mm usually yield the best results. We also have other scanning systems for larger parts.
- How do you present the measurement reports?
We provide color-mapped comparison reports, deviation analyses, GD&T measurement results, and CAD comparisons based on the scanned data. Reports can be delivered in digital formats such as PDF, STL, STEP, and IGES.
- Is optical scanning sufficient for reverse engineering?
Absolutely. Thanks to high-resolution scanning data, it is possible to create a detailed CAD model of an existing physical part. This facilitates production, improvement, or prototyping processes.
- How is optical scanning priced?
Pricing depends on the size and number of parts, required measurement accuracy, and the level of reporting detail. We offer various solutions from single-part jobs to mass scanning services.
