BINOCULARS Meaning and
Definition
-
Binoculars are a portable optical device consisting of two small telescopes fixed side by side, designed to enable enhanced vision for viewing distant objects. They are primarily used for observing objects or scenes that are too far away to be seen clearly by the naked eye. Binoculars consist of a pair of identical telescopes, aligned to transmit a parallel view of the same object to both eyes simultaneously.
Typically, binoculars are composed of a set of objective lenses at the front, gathering and focusing light onto a prism system or a series of lenses called the objective lens assembly. After being redirected, the light passes through the eyepiece lenses, bringing the image into focus for the observer. The prisms or lenses in binoculars aid in correcting the image orientation and aligning it in the proper orientation for the observer.
Binoculars are widely used in various activities such as birdwatching, wildlife observation, stargazing, hunting, and marine navigation. Their portability allows for easy transportation and quick deployment, making them a popular choice for outdoor enthusiasts and adventurers.
The optical power or magnification of binoculars is typically denoted by two numbers, such as "8x42." The first number represents the magnification, indicating how many times closer the viewed object will appear compared to the naked eye, while the second number refers to the diameter of the objective lenses in millimeters. This specification helps determine the field of view and light-gathering ability of the binoculars.
