Lenses for eyeglasses are generally made of CR39 (a thermosetting plastic) or polycarbonate, both of which are light in weight and do not break easily. Despite their advantages, these materials are relatively soft and reflective. They only attain the desired characteristics after surface treatment and finishing through applications of nano-coatings. This creates a hard, anti-reflective, and dirt repellent surface.
The biggest challenge in manufacturing quality eyeglass lenses is mass producing them cost-efficiently. The manufacture of such lenses can be completely automated by combining low-pressure plasma processes (application of the scratch-proof layer) and Openair® Plasma processes (for anti-reflection and anti-fogging coatings) in one manufacturing line.

Plasmatreat constantly faces shifting demands as a result of new ideas, regulations, and standards. Customers are increasingly approaching the company with unique and innovative project requests. Consequently, the capacities of the technology and research center will now be expanded to include a class-6 cleanroom.
Plasmatreat supports digitized manufacturing with its Plasma Control Unit (PCU) and makes numerous controls, regulation, and monitoring functions available to ensure consistently high surface-treatment quality and reproducibility.
VOCs occur when solvents and solvent-containing products are used, and they are harmful to the environment. Nevertheless, manufacturing in many industries still involves pre-treating surfaces with primers, bonding agents or other chemicals that release VOCs. With its Openair-Plasma process, Plasmatreat offers an environmentally friendly alternative.
