What is the resolution of a pair of binoculars?

Resolution is the measurement of a binocular’s ability to distinguish fine detail and produce a sharp image. Better resolution also delivers more intense color and often higher contrast.

Resolution varies in relation to the size of the binocular's objective lenses. Generally, a larger objective lens will deliver more detail to the eye than a smaller objective lens, regardless of the magnification of the binocular. Actual resolution is determined by the quality of the optical components, the type and quality of the optical coatings, atmospheric conditions, collimation, and the visual acuity of the user.
