What is the purpose of Binocular lens coatings?
All the optical components of Binoculars (lenses, and prisms) should be coated to minimize light loss and reflection problems inside the Binocular. A poorly coated Binocular can lose up to 50% of the light initially gathered through the objective lens, resulting in a poor quality image. By coating the optical components with a fine film of certain chemicals, light loss can be greatly decreased. The highest quality Binoculars have multiple coatings on all the optical components. These are known as “fully multi-coated” Binoculars. These Binoculars have the least loss of light and the result is a higher quality image.
