Anti-Reflective Coatings (AR)

Better Optical Quality and Appearance

All quality lenses whether in telescopes, binoculars, and your smart phone's camera, have an anti-reflective coating. 

  • Anti-Reflective (AR) Coatings, or "Non-Glare" coatings are designed to increase the optical quality of lenses by "pulling" more light through the lenses.
  • A lens without AR will typically reflect off about 20% of the light hitting it.
  • For eyeglass lenses this can look unsightly as people can see a lot of reflections off the front surface of the lenses.
  • AR coated lenses look almost totally clear with no reflections.

How do you know if a lens has an AR coating?

  • If you look at the lens straight on it will look very clear.
  • Held to a slight angle you will see a shimmer of color. The color can be a mix of blue, green, yellow, purple depending on the combinations of minerals used in the AR stack.
  • An AR stack is is the multiple layers of coatings that "pull" the light through the lens.
  • Different manufacturers have their own AR stacks. 
  • High quality AR coatings also have other layers of coatings that make the lenses more scratch resistant, block more UV, and make the lenses less easy to smudge and easier to clean (hydrophobic coatings).
