Finnish thin film coating specialist Picodeon Ltd Oy has developed its ultra-short pulsed laser deposition (USPLD) surface coating technology to be able to create either porous or dense aluminum oxide (Al2O3) coatings on heat-sensitive substrates for use in a wide range of industrial metallization applications.

Porous Al2O3 layers are used for instance as filters and electrical insulation layers. Dense Al2O3 is used as a barrier layer and is also an excellent optical coating with high transmittance properties.

The Picodeon process enables precise micro-structural control of Al2O3 coatings, and therefore coating characteristics, by the simple management and maintenance of coating process parameters on Coldab® Series4 USPLD batch process coating equipment.
