What are binocular binoculars?

binocular binoculars are two telescopes that are mounted together, allowing you to look at two lenses at the same time. This binary vision is beneficial because it mimics twice the eye vision of most living creatures. Binocular binoculars are commonly called binoculars, they can come in small, personal sizes and huge sizes.

This tool can be used in astronomy and observations of nature, depending on the strength of the magnification. Binoculary has become the basis of amateur sky and nature observers due to their cheap price and easy use. Small binocular binoculars are easily transmitted and can be held in their hands or worn around the neck. Binocular binoculars in large size require the use of a tripod. Most of the selections can be purchased in camera stores, electronic departments or sports shops.

Telescopes differs greatly in the energy and visual effect, with different models offering lenses of different sizes, different collection capabilitiesLights and various Magsíla nations. However, binocular binoculars are made of twins of the same exact specifications, which ensures that the view and magnification to the right is the same as the left. A pair of binocular telescopes consists of several parts: tubular case, two sets of lenses on each side, prism and focusing controls.

users look through the pipes of the housing through the first lens, known as the eyepiece. At the end of the tube is a second lens, known as the lens lens. The lens is responsible for gathering light, increasing images and focusing their focus. There is a prism between two lenses, a mirror that reverse the image orientation and shortens the observed distance. The button or focus dial can be on the top of the housing.

The optical design of binocular telescopes is often the most important characteristic of one model from another. BinocularBinoculars come in three different optical samples: the prism of the roof, the prism of the porra and the reverse prism of the Porra. The design of the roof prism relies on linear properties and even gaps; Narrow barrels, eyepieces and lenses are mounted in a straight line by the same distance from each other. The focus is internal, not the outer, for the prismatic fringe of the roof, which allows users to move the lens inside their housing to focus. The big advantage of this simplified design is that the roof binoculars are often waterproof, allowing use in any type of weather or environment.

Binoculary Porra Porra Prism is heavier and larger than the roof prism models. This design is not evenly distributed, arranging eye eye eye on each other than lenses lenses. The focus controls are on the outside of the binocular case, allowing only external focus. This design is the most common and traditional design of binocular telescopes. Despite the Tomume aboveUnpleasant features, this design allows a large amount of deep perception and light. It is also usually the least expensive design.

Reverse Porra Prism Binoculars assembles lenses closer to each other than eye eye pool - this is the opposite of Porra Prism design. Among the smallest binocular binoculars, the prism models do not work well if the long distance, magnification and depth are needed. They have external focus controls and are usually not waterproof.
