What is the difference between the different binocular coatings?
The optical parts of a binocular have different coatings applied to them. Below are the different coatings applied to binoculars and how they benefit the binocular. Coated: A single layer of coating on at least one lens surface. Coated optics help to reduce glare. Fully Coated: A single layer of coating on all air-to-glass surfaces. Fully Coated optics have improved glare reduction over coated optics. Multi-Coated: Multiple layers of coating on at least one lens surface. Multi-Coated optics help to reduces glare and increase contrast & clarity Fully Multi-Coated: Multiple layers of coating on all air-to-glass surfaces. Fully Multi-Coated optics exhibit improved reduces glare and futher increased contrast & clarity Phase Coated: Chemical coating applied to roof prisms, porro prisms do not benefit from this particular coating. Phase Coatings are the highest quality coatings maximizing glare reduction, optimized light transmission, and enhanced contrast & clarity.
