n[pl] field glasses
Binoculars, field glasses or binocular telescopes are a pair of identical or mirror-symmetrical telescopes mounted side-by-side and aligned to point accurately in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects.
Unlike a monocular telescope, binoculars give users a three-dimensional image: for nearer objects the two views, presented to each of the viewer's eyes from slightly different viewpoints, produce a merged view with an impression of depth.
Most early binoculars used Galilean optics; that is, they used a convex objective and a concave eyepiece lens.
An improved image and higher magnification can be achieved in binoculars employing Keplerian optics, where the image formed by the objective lens is viewed through a positive eyepiece lens (ocular).
Porro prism binoculars are named after Italian optician Ignazio Porro who patented this image erecting system in 1854 and later refined by makers like the Carl Zeiss company in the 1890s.
Binoculars have a focusing arrangement which changes the distance between ocular and objective lenses.
Since a typical binocular has 6 to 10 optical elements with special characteristics and up to 16 air-to-glass surfaces, binocular manufactures use different types of optical coatings for technical reasons and to improve the image they produce.
