Organic AR Coating

**Griff** · 07-31-2008, 06:34 AM

I heard Sears is selling an organic AR coating with no reflect color. Does anyone know what coating that is or what company sells it?
Has anyone had any experience with it or seen it? Is it any good?

Thanks in advance for your replies.

Resolution is offering a clear AR coating on Poly

What is an organic ar coating? They all contain carbon molecules.

Everywhere outside the US, glass lenses are called "mineral", and non-glass lenses are called "organic". Perhaps the "organic" is used in that context.

Thanks for the info. I did not know that. The new clear AR coatings are very interesting, whatever they're called. The mineral designation I can understand. Glass lenses are made from melted minerals, which are also organic. Maybe they mean that it's produced by hippies in Oregon?

Typically A/R coatings are manufacutured using Inorganic materials like Quartz and Zirconium. Organic A/R coatings are usually dip or spin coated and are made using lacquers with different refractive index's. In the far east stock lenses are made this way. Seiko also released a product in Japan which is an organic A/R coating which is tauting a high level of temperature resistance along with good A/R coating properties and scratch resistance.

sorry but the dip or spin coated are SIO2 based (for high index some Ti3O5 too), so are not "organic" (the SiO2 are coming from a sillossano alcool but it is sot the final product). In any case in europe we use speaking of "organic substrate" all the plastic lens (not poly and mineral), so when we speak arround organic AR we speak of the standar AR (SiO2/ZrO2/Ti3O5...)
