Small and portable

There is no excuse not to have binoculars. Because at just 160 grams and particularly small the Jupiter III Universal binoculars are suitable in different situations. BaK4 prisms and multi-coating on the built-in lenses, give this optical mini an exceptionally high contrast-rich, bright view.

Jupiter III is the perfect partner for sporting events, concerts, as well as for hiking and travelling.

Magnification

The first number in the product name indicates the magnification. For model Jupiter III 8x21, this is the 8x, and means that you see with this binocular an object 8x larger than with the naked eye. In general: the higher the magnification the smaller the field of view. For vierwing over a long period, the recommendation is generally a maximum magnification of 10x. Larger magnifications make it more dificult to keep the binoculars still and prevent image shake whilst viewing.

Objective diameter

Diameter of the front lens of the binoculars. In our example model Jupiter III, this is the second number in the product name on the lens and is in mm. In this case 21mm. The larger the objective lens is, the more light into the binoculars, especially important if binoculars or a spotting scope are to be used in low lighth. However, large lens diameters increase the weight, size and construction cost.

Exit pupil

The exit pupil is the small bright area that is seen in the eyepiece of the binoculars. It should be circular and is measured in mm. (Note: If this shape appears hexagonal rather than round, this is an indication that an inferior prism was used.) Calcuinlagt the size of the exit pupil is found by dividing the objective diameter by the magnification value. For model Jupiter III, this results in an exit pupil of 2.62 mm. IMPORTANT: For comfortable use, binoculars should align both the size of the exit pupil and the pupil size of the user as closely as possible. The pupil diameter of the human eye changes with age.
