Binoculars 3x30

Describes the internal structure of a pair of binoculars, thereby further subdividing the different types.

A compact and modern binoculars design, in which the objective lens and the eyepiece lie in a straight line.

The second specification in the binoculars’ model number is the front lens diameter. The larger it is, the more light the binoculars collect.

Binoculars are focused by focusing on the object, or rather the eyes of the observer.

The sharpness is adjusted via a central focusing wheel.

These eyepieces have a relatively large eye relief. It is possible to wear spectacles while observing and still benefit from a comfortable viewing position.

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.
