How To Evaluate Optical Quality

The brilliance and sharpness of the image you see through a particular binoculars is determined by a number of different factors. Magnification, optical coatings, and lens diameter are just a few of the factors influencing how a binoculars performs. However, the single most important criteria in performance will always be the quality of the optics.

 

Factors To keep In Mind When Choosing A Binoculars

Magnification

Magnification is the degree to which the object being viewed is enlarged. The level of power affects the brightness of an image, so the lower the power of a binoculars, the brighter the image will be.

Diameter (Objective Lens)

The objective lenses of binoculars are the larger lenses in the front of the binoculars that the light passes through. The diameter of one of these lenses, given in millimeters (mm), will be the second number describing a particular binoculars. The diameter of the lens determines the light gathering ability of the binoculars, with the greater light gathering ability of a larger lens translating into greater detail and image brightness.

Field of View (FOV)

The size of the area that can be seen while looking through the binoculars is referred to as the field of view.  The angular field of view is usually indicated on the outside of the binoculars, in degree. The linear field of view refers to the area that can be observed at 1000 yards (m), and is expressed in feet (m). A larger field of view translates to a large area seen through the binoculars. Field of view is related to magnification, with greater magnification creating a smaller field of view.

Resolution

Resolution is measurement of a binoculars’ ability to distinguish fine detail and produce a sharp image. Better resolution also delivers more intense color. Resolution is related directly with size of objective lenses. Generally, a larger objective lens will more detail to the eye than a smaller objective lens, regardless of the magnification of the binoculars. Actual resolution is determined by the quality of the optical components, the type and the quality of the optical coatings, atmospheric conditions, collimation, and the visual acuity of the user.
