Microscatt®
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?
Engraving characteristics
Perfectly repeatable
Burr-free process
Small roughness values
Controlled by algorithm
Diffusion characteristics
High-quality diffusion
Great luminance
Good anisotropy level:
avoid hotspots or stripes
3D Design
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
ENVIRONMENTAL BENEFITS
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
DESIGN BENEFITS
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
COST-EFFECTIVE SOLUTION
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?
1
SIMULATION AND DECISION
Simulate the references with the BRDF/BTDF files and decide which is the best for your requirements.
2
TEXTURE ENGRAVING
Microrelleus will engrave the desired area on the production tool.
3
PLASTIC INJECTION
No need of more steps, mold is ready for production.
Ask us for the samples or BRDF/BTDF files to simulate our Microscatt® technology
