The inner world of binoculars

The inner world of binoculars

Reflected light rays pass through the objectives (lenses facing the object) into the inner part with a focused beam and through a system of prisms are corrected before reaching the eyes through the eyepieces (lenses facing the observer).

The eyepiece, consisting of up to 6 lenses, acts as a magnifying glass.

The 7x50 numbers found on classic marine binoculars represent 7x magnification and 50mm lens diameter.

Parts designation:

1. The structure of one side of the binoculars in section

2. The roof-shaped prism system is very compact but relatively expensive and contributes to a compact size.

3. The porprism system is mainly used in marine binoculars, characterized by a typical broken shape that fits comfortably in the hand.

4. A system of lenses moves along the length of the axis in the eyepiece, due to which the sharpness of the image is established.

5. The width of the field of view is set in relation to 1000 meters to the distance of the object.
