What’s PVD?

Acronym of Physical Vapor Deposition, PVD is the under vacuum technology of applying a thin film of material, typically metals, metal oxides and other compounds of a few microns of thickness, on to a substrate material or object.

The aim is to form a thin, bonded surface layer that greatly improves appearance and properties of the substrate, for both Decorative and Functional purposes.

ODL’s coatings are deposited through PVD processes by Evaporation technology from a melting source, and by Sputtering technology, through atoms injection from a solid source bombarded with ionized gases.

Advantages of PVD Coatings

  • High durability and abrasion resistance
  • No corrosion, oxidation, or blackening
  • Chemical inertness to aggressive environments
  • Inalterability to UV light
  • Many finishes and colors
  • Wide innovation possibilities
  • High degree of repeatability
  • Eco-friendly


Committed to the environment

PVD is certified for meeting environmental regulations and being the sustainable and cost-effective alternative to polluting paints and galvanic finishes.

Not only is PVD more sustainable from an environmental point of view, but also from an innovation and competitiveness perspective. PVD is the preferred choice when it comes to quality, durability, and sustainability.

Compliant with REACH and RoHS regulations
Chemical-free and waste-water free production
No harmful emissions

ODL Company

The history of ODL (Optical Deposition Laboratory) begins in 1987 with the foundation of a research laboratory by two physicists in Bergamo (Italy) having years of experience in the thin film coating technology for optical applications.

Today, ODL has grown into an international high-tech enterprise, with advanced equipment and 40 high skilled professionals working in a dynamic and customer-oriented organization, with offices in Italy and China.

In 2006, the company opened a branch in Guangzhou (China) devoted to products cutting and shaping finishing for Asian customers who require Made in Italy products that meet the specific requirements of their local markets.

The production capability is over 900 sqm of glass coating per month.

Through its projects ODL operates in 5 continents.
