Types of Binoculars:

Standard Binoculars can be used for everything from nature observation to spectator sports.

Compact Binoculars are smaller and lighter in weight, and are a good choice to take along to the theater or concerts, or on hikes and hunting trips.

Wide Angle Binoculars are ideal for tracking fast-moving action across wide areas such as football fields, racetracks and wilderness terrain.

Zoom Binoculars let you increase the magnification when you want to get in close for details. From distant to near view, you get the best of both worlds.

Waterproof Binoculars deliver clarity despite foul weather conditions including fog, rain and ice. O-ring sealed and nitrogen-purged for reliable fogproof, waterproof performance.

Binocular Terminology

Coated Optics
Coatings on lens surfaces reduce light loss and glare due to reflection, resulting in a brighter, higher-contrast image with reduced eyestrain. There are 4 levels of coating:

Coated: A single layer on at least one lens.
Fully-Coated: A single layer on all air-to-glass surfaces.
Multi-Coated: Multiple layers on at least one lens.
Fully Multi-Coated: Multiple layers on all air-to-glass surfaces.

PC-3 Phase Coating
Found on the best roof prism binoculars, this coating enhances resolution and contrast.

Diopter Control
Most binoculars have one eyepiece that adjusts to compensate for vision differences between right and left eyes.

Exit Pupil
The exit pupil refers to the size of the circle of light visible at the eyepiece of a binocular.
The larger the exit pupil, the brighter the image. To determine the size, divide the objective lens diameter by the power (an 8x32 model has an exit pupil of 4mm).

Eyecups
Bausch & Lomb® and Bushnell® binoculars come with twist-up, pop-up or soft rubber fold-down eyecups. These options allow everyone, including eyeglass wearers, to see the entire field of view.

Eye Relief
Eye relief is the distance a binocular can be held away from the eye and still present the full field of view. Extended or long eye relief reduces eyestrain and is ideal for eyeglass wearers.

Field of View (FOV)
Field of view is the side-to-side measurement of the circular viewing field or subject area. it is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide field of view is better for following action. Generally, the higher the magnification, the narrower the field of view.

 

Focusing Systems

InstaFocus®: A paddle or rocker bar between the barrels adjusts the lenses.
Center Focus: A focus wheel between the barrels moves the lenses.
PermaFocus®: No focusing needed. The focus is preset for a typical subject distance.

Magnification (Power)
Binoculars are often referred to by two numbers separated with an "x". For example: 8x32. The first number is the power or magnification of the binocular. With an 8x32 binocular, the object being viewed appears to be eight times closer than you would see it with the unaided eye.

Objective Lens Size
The second number in the formula (8x32) is the diameter of the objective or front lens. The larger the objective lens, the more light that enters the binocular, and the brighter the image.

Zoom Binocular
A binocular with a variable power range, for example: 8-20x. Magnification is changed with a convenient lever or knob.

Near or Close Focus
The closest you can be to an object and maintain visual clarity.

Prism Glass
Most optical prisms are made from borosilicate (BK-7) glass or barium crown (BAK-4) glass. BAK-4 is the higher quality glass yielding brighter images and high edge sharpness.

Prism Systems
Binocular prisms turn what would be an upside-down image right-side up.

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, streamlined shape in which the lenses and prisms that magnify and correct the image 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.

Resolution
Resolution, or definition, is the ability of a binocular to distinguish fine detail and retain clarity.

Waterproof/Fogproof
Some binoculars are sealed with o-rings and are nitrogen-purged for waterproof and fogproof protection. These models are able to withstand complete immersion and remain dry inside.
