Plastic Lens Process
 New advanced thin film AR coating for plastics
Safire2 has been developed to provide a high quality, durable broadband antireflection coating to all the latest lens materials. The process utilises modern techniques in dip-hard coating along with advanced plasma thin film deposition to allow all types of lenses to be coated to an outstanding quality.
Safire2 hard coat process prepares the uncoated lens for high quality optical coatings in two ways. Firstly, it ensures all surfacing and polishing defects are covered; secondly, it hardens the surface sufficiently to allow the plasma deposition of an extremely durable antireflection coating stack.
Outstanding optical transmission
Safire2 reduces reflection from each side of a CR39 lens from approximately 4% to below 0.4% average (400nm-700nm). This is nearly 50% less reflection than most commercially available AR coatings.

Incorporates advanced top coat chemistry.
The Safire2 AR coatings exhibit a very smooth dense surface structure compared with standard commercially available coatings. This smooth film combined with Safire2 reactive super top coat makes lens care and cleaning much easier.
The Safire2 top coat chemically reacts with the final layer of the AR coating stack and exhibits no clear interface due to being index matched. This ensures that the coating remains on the lens and optical performace is not impaired.
