Precise reference marks for laser scanners, 3D scanning & industrial surveying

These standard 3 mm diameter adhesive points are among the most widely used reference marks in professional laser scanning , photogrammetry , 3D scanning , industrial surveying and reverse engineering .
Thanks to their highly reflective, retroreflective surface, the dots are reliably detected even by high-resolution laser scanners – even on dark, glossy or complexly shaped surfaces.

The self-adhesive backing allows the markers to be applied quickly, securely and without residue to almost any material: metal, plastic, paint, carbon, fiberglass reinforced plastics, ceramic or matte surfaces.

These 3mm adhesive points are the ideal choice when the highest precision is required for detailed measurements, contours, smaller components and tight geometries.

Frequently Asked Questions (FAQ)

How many adhesion points are needed for a 3D scan?

Typically, 150–600 pieces are required per component, depending on size and complexity. Significantly more may be needed for series production and assemblies.

Are 3 mm or 6 mm better?

3 mm is ideal for small components and detailed areas.
6 mm is suitable for large objects, higher scan distances or coarse geometries.

Do the markers also adhere to plastic or painted surfaces?

Yes, the dots adhere to almost all smooth surfaces – including plastic, carbon, paint, metal and fiberglass.

Can the adhesive points be reused?

For optimal measurement accuracy, single use is recommended.

Are they compatible with my scanner?

Yes, retroreflective markings are supported by all well-known manufacturers.
