Microstructure for light homogeneity in tail lenses

CUPRA FORMENTOR 2024
Microstructure for light homogeneity in tail lenses

Customer request and Microrelleus' feedback

Cupra shares with Microrelleus the idea to introduce microstructuring for a new concept of tail lenses. The purpose is to reach light homogeneity from a perpendicular placed light source.

Micro-prisms concept for light distribution

Microrelleus state-of-the-art femtosecond laser engraving allows free-form design over any 3D shape with homogenous finishing.

PMMA prototype engraving

Microrelleus engraves 3D shape PMMA prototype to achieve the correct microstructuring for light homogeneity.

The goal is to obtain a functional prototype.

Ultra-precise production tool insert microstructuring

Homogeneous finishing, sharp edges, excellent tolerances and high quality surface finishing on the engraving of the production tool inserts.

Microscatt® technology on production tool inserts

Achieve control of light diffusion in the desired areas of the part thanks to Microscatt® technology which is engraved in the production tool inserts.
