Binoculars are also called as field glasses. They are two telescopes that are mounted side by side to view distant objects effectively. There are different types of binoculars available on the market such as compact binoculars, wide angle binoculars, and image stabilizing binoculars.
Types of binoculars on the basis of prism system
Binoculars are available in mainly two different types of prism systems. One is porro system and other is roof prism system. In Porro prism-based binoculars, the objective is offset from the eye. These binoculars provide enhanced depth perception and a wider FOV (field of view) In roof prism device, the prisms closely overlap each other. This enables objective lens to get inline with the eyepiece. When the lens and the prism are in the same line, you get a slim and streamlined image. This makes them useful for scouting.
General classification of binoculars:
Standard Size Binoculars
A standard binocular is also referred as full-size binocular. It is designed for multipurpose use to capture everything ranging from spectator sports to nature specific observation.
This binocular is small in size and light in weight. It is the best choice for people, who want to take it along with them to the concerts, theater, hikes or on hunting trips.
Wide Angle Binoculars
Such binoculars are best suited for tracking quick moving action that takes place in largely spaced areas such as racetracks, football fields, and wilderness terrain.
These binoculars come with an added zoom functionality that enables the user to enhance the magnification to better focus on the details. Whether you are looking for a distant view or near view, it is the best binocular that gives the benefits of both worlds.
Waterproof binoculars are best when you want clarity in spite of poor weather conditions such as rain, fog and ice. Nitrogen purged and O-ring sealed binoculars offer exemplary resistance towards fog and water.
This binocular comes with a housing that is completely covered using rubber or synthetic material. Armoring protects the device from any possible scratches that it can get with use. It provides grip to the user to hold it comfortably. Armoring prevents any noise when binocular bangs against something.
Central focus binocular
One wheel is used in this binocular to aim on objects. It can easily focus on close as well as distant objects well. This makes it versatile device.
No Focus Binoculars
This is an affordable alternative to an “individual eye-piece focus binocular.” The difference is that here the eyepieces are fully locked. As they are properly set at the factory, they can’t be adjusted. This implies that you won’t be able to focus on objects near than 40 yards away. Also, it implies that one can’t adjust the binocular for differences between the right eye and left eye strength.
Everyone has a different expectation from binoculars. Due to this reason, you will find different type of binoculars with different features in-built into it. So, gaining in-depth information about the technical and performance aspects of binocular will help you buy the right one.
