Eye Piece

Binoculars are used for viewing distant subjects. It has two identical and aligned glasses in the same direction. It comes in different types and styles, serving different purposes.

"Binocular" comes from the Latin word "bini" which means "double," and "oculus" meaning "eye." The advantage of using two eyes with the use of this gadget is that it gives a wider view.

These gadgets are more commonly used by astronomers, hungers, navigators, sports fans watching a game, travelers, and militaries.

Different types of binoculars:

• Galilean binoculars - this binocular has the advantage of giving erect images. However, its capability of viewing wider images is limited. It cannot be used for high magnification. It also has two eyepieces, a convex objective and a concave eyepiece lens.

• Porro prism binoculars - the inventor Ignazio Porro, an Italian optician, designed this binocular. He used objective lenses separated off-set from the eyepiece. This maintains a folded optical path for wider and clearer views.

• Roof prism binoculars- this was designed by Achille Victor. This features an erected image. It also folds the path, making the object aligned with the eyepiece.

• Porro vs. Roof prisms - this was made for reducing the light transmission to about 12%. Porro prism binoculars also give brighter images. However, this binocular also features a similar magnification object size and optical quality.

Binoculars are useful in many fields. In astronomy, specialized lenses and gadgets are being used to enlarge and emphasize very distant objects from the sky.

Binoculars started in the 1970s and became must-have gadgets almost instantly. Some prefer buying branded ones with trusted quality and durability. What is important however is to be knowledgeable about the varieties to make sure you are buying the right model.

Check the magnitude of the glass surfaces. Some coatings are designed to reduce the glare of a bright light, as seen through the eyepiece. The common magnification is 7x50 or 8x25. The first digit refers to the number of zoom you can do and the second is the distance or the diameter from the front object you are attempting to view.
