| A binocular consists of two optical systems that are joined by a hinge and (typically) share a common focusing mechanism. The ability to create an image for both eyes simultaneously provides a realistic perception of depth. Binoculars are available in a great variety of sizes, magnifying powers and features to suit any purpose or preference. Check out the below image for more details.

|
|
Standard Binoculars |
A standard or full-size binocular can be used for everything from nature observation to spectator sports. |
|
Compact Binoculars |
Compact binoculars are smaller and lighter in weight and are a good choice to take along to the theaters or concerts or on hikes and hunting trips. |
|
Wide-Angle Binoculars |
Wide angle binoculars are ideal for tracking fast-moving action across wide areas such as football fields, racetracks and wilderness terrain. |
|
Zoom Binoculars |
A zoom binocular allows the user to increase the magnification in order to focus in on the details. From distant to near view, it´s the best of both worlds. |
|
Waterproof Binoculars |
Waterproof binoculars deliver clarity despite foul weather conditions including fog, rain and ice. O-ring sealed and nitrogen purged for reliable fog proof, waterproof performance. |

|
Lens surface coatings reduce light loss and glare due to reflection for a brighter, higher-contrast image with less eyestrain. |
|
Types of Coatings |
|
Coated |
A single layer on at least one lens surface. |
|
Fully Coated |
A single layer on all air-to-glass surfaces. |
|
Multi-Coated |
Multiple layers on at least one lens surface. |
|
Fully Multi-Coated |
Multiple layers on all air-to-glass surfaces. |

|
|
Insta Focus |
A paddle or rocker bar between the barrels adjusts the lenses allowing for rapid focusing adjustment. Ideal for following subjects in motion. |
|
Center Focus |
A focus wheel between the barrels moves the lenses. |
|
Perma Focus |
Does not require focusing. The optics are preset and optimized for distant subjects and fine focusing is achieved via the users eyes. |

|
|
The prism system of a binocular reduces the size needed to provide focal length and turns what would be an upside-down image right-side-up. There are two types of prism systems, roof and porro. |
|
Types of Prism Systems |
|
Roof Prism System |
In roof prism binoculars the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, stream-lined shape in which the lenses and prisms are in a straight line. |
|
Porro Prism System |
In porro prism binoculars the objective or front lens is offset from the eyepiece. Porro prism binoculars provide greater depth perception and generally offer a wider field of view. |
