Binoculars Fernglas Vantage 10x32

The eye relief specifies the maximum distance from the eyepiece at which the entire field of view can still be seen. A suitable distance for spectacles wearers is >16mm.

The interpupillary distance indicates how far the eyepieces or tubes can be pushed together or pulled apart. This is an important indication, since each person has a different interpupillary distance.

The first number in the binoculars’ model number represents the magnification. It specifies how much larger an object appears compared to when viewed with the naked eye.

Relates to the beam of light emitted by the eyepiece. The exit pupil is closely associated with the brightness of a pair of binoculars.

Watertight optics are equipped with special seals and are gas-purged. This is usually with nitrogen or argon gas. Since these gases are heavier than air, they cannot escape.
