Coating Processes

The performance and durability of ophthalmic lenses is largely determined by the coating package applied. Satisloh offers a wide variety of durable hard coatings, innovative anti-reflection (AR) & Multi-layer coating stacks, state-of-the-art top coating solutions, and in-chamber tinting for ophthalmic lenses in all materials.

Lens performance depends on the combination of hard coat, AR coat and top coat. Only the best combination of all three, suited for the specific lens material, allows us to meet the needs of every production environment and all customer requirements.

Hard Coat

The performance and durability of ophthalmic lenses starts with leading scratch resistance technology. Satisloh offers thermal dip coating and UV spin coating processes for hard scratch-resistance and highest anti-reflective adhesion on ophthalmic lenses.

Multi-Layer Stacks

Satisloh offers standard anti-reflective (AR) coatings to enhance appearance, improve clarity of vision and reduce reflections on ophthalmic lenses. Beyond these we offer specialty coatings for UV and Blue Light protection, reduced of night vision glare, as well as multiple mirror and in-chamber tinting coatings.

Top Coat

Easy cleaning is one of the most important features of AR coated lenses. Without a top coat, the lens is rough, attracts dirt and water and is tougher to clean. There are a number of top coat options to choose from and theses are applied on top of the AR coating inside a vacuum chamber.
