Micro-texture for light scattering control
After years of development we achieved our Microscatt® technology. We use femtosecond laser micromachining to engrave our own designed, controlled, stable, repeatable and homogeneous micro-textures and microstructures on the tool to control the light diffusion on the final injected part.
Why do we use femtosecond laser to engrave our Microscatt® technology?
Small roughness values
Controlled by algorithm
Good anisotropy level:
avoid hotspots or stripes
Confocal microscope image of the engraved structure
Photometry analysis of injected parts on identical conditions but different engraved Microscatt® references
Elliptical diffusion: elliptical formats available with good anisotropy level to avoid hot spot or stripes.
Circular diffusion: homogeneous formats at different levels of luminance and diffusion.
We are able to remove hot spot and diffuse the light both in circular and elliptical formats.
You can prioritize homogeneity, luminance and angle opening in both directions depending on the chosen reference.
Benefits of Microscatt® technology
Material reduction because diffusion is independent from material thickness
Easy to recycle by using monocomponent material without particles
Easy to recycle by avoiding added films
Beautiful surface finishing with almost invisible pattern
Possibility of controlled diffusion on ultra thick pieces
Possibility of engraving 3D curved tools
100% digital process: free-form design area
Energy reduction: possibility of less LED
Reduction of injected material and weight
No need of expensive diffusers or films
Processes simplification: tool engraving + injection
Microscatt® technology, how it works?
SIMULATION AND DECISION
Simulate the references with the BRDF/BTDF files and decide which is the best for your requirements.
Microrelleus will engrave the desired area on the production tool.
No need of more steps, mold is ready for production.
