Scope Coatings

A good quality scope should be water resistant, fog proof and shock proof. A large selling point is coating on the optical lenses. The optical coating on the lens will maximize light transmission into the optics, reduce the loss of light due to reflection, add some scratch resistance and reduce glare. There are several levels of coating.

  • Coated: There is at least one layer of protection on at least one lens surface. This can mean that only one lens has a coat.
  • Fully coated: The scope will have a single layer on all air to glass lens.
  • Multi-coated: The scope will have a single layer on all air to glass lens with multiple coats on at least one lens.
  • Fully multi-coated: This scope will have multiple layers of coating on all air to glass lens.

These coatings are intended to help minimize scratches, fog and the accumulation of water on the lenses. No coating is 100% effective and depending on atmospheric conditions, environment and type of use these coating should at least help. It is smart to always purchase a scope within your price range that has the best coating possible.
You can also do other things to protect your scope and to ensure it is ready when the time to take that shot arises. The purchase of a scope cover to protect the mounted scope is a great idea. We all know the misadventures in hunting that can and will occur and its best to protect your investment. There are also lens covers that protect the lenses when not in use. Just a small investment of money can increase your scopes survivability and usability.
