Abstract

There are three main parts to a binocular’s optical system: Objective lens assembly. This is the lens assembly at the “big end” of the binocular. Its function is to gather light from the object and to form an image at the image plane.

    There are different conventions for the use of “convergence” (and “divergence”), depending on whether the optical axes of the binocular are converging or the optical axes of the eyes are converging (to accommodate the diverging optical axes of the binocular). The usage here is the latter. It is simple to tell which convention is being used: the greater value is for converging eyes (diverging binoculars).
