Glossary objective lens diameter determines the amount of light that penetrates the objective lens of binoculars or spotting scopes. The larger the diameter, the greater the amount of light that enters the optical system, and the brighter the image. Field of view: when looking through binoculars or spotting scopes, a circular image appears. The width of this image is referred to as the "field of view". For binoculars and spotting scopes the field of view is being measured in m/1000m. The corresponding figure indicates the width of the area visible at a distance of 1000 m. The higher the magnification, the smaller the field of view.
