Terminology
Move your mouse over any of the above terms to learn more about it.
- n/axMagnification: Magnification The magnification of a binocular refers to how many times larger an object appears. For example, with a 10x magnification an object 1000 yards away would appear to be only 100 yards away.
- n/aObject Lens Diameter:
Objective Lens
The objective lens is the larger of the outer lenses in your binoculars. These lenses are what gather
all the light that you see; the bigger the lens the more light allowed in. A larger objective lens also tends to provide
better resolution and more detail than a smaller one. The sizes range from a tiny 15mm for theater glasses to 50mm and
larger for low-light and spotting binoculars.
Tip: While larger lenses allow more light in, they also make the binoculars heavier. Consider how long you may be holding the binoculars, or if you will be using a tripod. - n/a mmExit Pupil:
Exit Pupil
The size of the image as seen from the binocular's eyepiece. This is the circle of light seen in the
eyepiece seen from about 10 inches away. Commonly used as a measurement of how bright the binoculars are. You can figure
out the exit pupil diameter by dividing the objective lens diameter by the magnification power. 10x50mm binoculars would
have a 5mm exit pupil.
Tips: A binocular works best when the exit pupil diameter matches your eye's pupil diameter. A smaller diameter of around 2-3mm is good for binoculars for bright daytime use. Larger exit pupils of around 7mm are good for low light conditions and star gazing. - 0°Angle of View:
Angle of View
The Angle of View is the angle between the left and right edges of the field of view from the
binocular's point of view. This angle will generally get smaller with greater magnification.
Tip: Binoculars vary, some will have a wider angle of view than others of the same magnification. - n/a°Apparent Angle of View: Apparent Angle of View The Apparent Angle of View is the angle of view with the binocular's magnification figured in. This is simply the angle of view multiplied by the magnification. For a 10x magnification and a 5° angle of view the Apparent would be 50°. This is directly related to the Field of View, but is often used to compare binoculars.
- n/aField of View(@1000yrds):
Field of View
Field of view is a measurement of the area visible at a given range. So with a pair of 8x binoculars
you may be able to see an area 330 feet wide from a range of 1000 yards.
Tip: Binoculars vary, some will have a wider field of view than others of the same magnification. - n/aEye Relief:
Eye Relief
This is the distance that the binocular can be held from your eyes and still provide a good image.
A longer eye relief is better for eyeglass wearers, as it will allow them to continue to wear their glasses while
viewing.
Tips: A longer eye relief is generally preferable, but a simple solution, though not always used, is having adjustable eye cups. These can usually make up for shorter eye relief, which is common in lower end binoculars.
- n/aBrightness Index: Brightness Index This is the square of the exit pupil diameter. A 3mm exit pupil binocular would have a brightness index of 9. This is a common way to measure the brightness of a binocular.
- n/aMinimum Focusing Distance:
Minimum Focusing Distance
This is the minimum distance that the binoculars can render a clear image.
Tips: The short minimum focusing distance is nice when viewing nature, going to the museum, etc. It is not of paramount importance in buying binoculars but as with everything else, it depends on how you plan to use them. - n/aLength: Length Length of the binoculars is measured from the objective lens to the eyepiece.
- n/aWidth: Width Width of the binoculars is measured from the left side to the right side of the binocular at it's widest point.
- n/aHeight: Height Height is measured from the bottom of the binoculars when laying down flat to the highest point on the top.
- n/aWeight: Weight Weight is an important consideration when buying a new pair of binoculars. You should consider how long you will be holding them up to your eyes, and whether or not you intend on using a tripod. Larger objective lens binoculars will weigh more than smaller lenses. Also higher quality binoculars tend to weigh more due to higher grade materials used.
- n/aInterpupillary Distance:
Interpupillary Distance
The distance between the centers of a person's pupils. Every binocular has a range of movement, by
pulling the barrels inwards/outwards, to accommodate different IDs - e.g. "56-72mm" means the minimum ID is 56mm and the
maximum ID is 72mm. If your ID is 54mm you will have difficulty seeing through such a binocular because the barrels will
not line up with the centers of both your eyes.
Tips: Most binoculars have an adequate interpupillary distance range for most people. However, if children will be using the binoculars often you may want a binocular with a minimum ID of around 56mm or below.
