Standard adhesive dots 3 mm black/white suitable for structured light scanners 10,000 pieces

Universal contrast markers for optical 3D measurement systems, component registration and precise surface analysis

These standard 3 mm diameter adhesive dots are one of the most universal marking formats for structured light scanners , fringe projection measuring systems and optical registration methods.
The clear black and white contrast design ensures that the points are reliably identified by the recognition algorithms of modern 3D scanners and serve as a stable basis for object registration, area assignment and precise position detection.

With their self-adhesive backing, the markers can be placed on almost any smooth surface – from plastic to metal, from painted surfaces to finely structured workpieces.
Thanks to their size, they are ideally suited for medium-sized components, technical components, series measurements and measuring fields with high accuracy.

The bulk pack of 10,000 pieces is ideal for manufacturing plants, laboratory environments, development departments and measurement service providers.

Product features

3 mm diameter – universal standard size

Clearly visible for optical measuring systems, yet compact enough for components with medium detail depth.
Perfect for components where micro-dots would be too small and larger markers too dominant.

High contrast black/white

The two-color pattern ensures stable and unambiguous brand recognition – regardless of component color or surface structure.

Self-adhesive backing

Easy to use: stick it on, scan it, remove it without leaving any residue.
Suitable for sensitive or coated surfaces.

Compatible with common optical 3D scanners

Compatible with:

• Structured light scanners (GOM, Shining3D, Polyga, RangeVision, etc.)

• strip lighting systems

• Optical measurement methods that use marker tracking

• High-resolution desktop scanners and laboratory equipment

Bulk pack: 10,000 markers

Ideal for extensive measurement projects, larger assemblies or recurring testing procedures.

Application areas

1. 3D measurement of medium-sized technical components

Ideal for housings, fixtures, plastic parts, machine elements and prototypes.

2. Object registration in optical measuring systems

Ensures clear assignment of individual scan images and stable tracking conditions.

3. Quality control & serial testing

Can be used for comparative measurements, sample checks and automated evaluations.

4. Design & Development Projects

Important for reverse engineering, CAD matching and surface reconstruction.

5. Applications with complex geometries

The markers are particularly suitable for curved, angular or textured surfaces.

Advantages of the 3 mm black/white adhesive dots

Universally applicable

The 3 mm size is considered a standard size in many quality control and research applications.

Stable optical detection

The strong black/white contrast ensures reliable evaluation by optical algorithms.

Clean and gentle on surfaces

Self-adhesive, removable without residue – ideal even for sensitive materials.

Ideal for medium detail sizes

It does not obscure any geometries, but offers a clearly recognizable marking area.

Efficient for large production runs

10,000 pieces provide enough material for extensive measurement series.

Technical data

FAQ – Frequently Asked Questions

When should you use 3mm markers instead of 1.5mm or 6mm markers?

3 mm is ideal for medium-sized components where micro dots are too small and 6 mm markers are too large.

Are the points detected by all structured light scanners?

Yes, they are designed for contrast-based recognition algorithms.

Can the markers be used on painted or coated surfaces?

Yes, they adhere securely and can be removed without leaving any residue.

Are the markers suitable for serial measurements?

Yes, the 10,000-piece bulk pack is ideal for continuous processes in quality assurance and development.
