MODE D'EMPLOI 8X21 JUPITER III PENTAX
PENTAX Binoculars
Jupiter III

SMALL AND PORTABLE
There is no excuse not to have binoculars. Because at just 160 grams and particularly small the Jupiter III Universal binoculars UfY suitable in XJZYfYbhg]h Uh]cbg. 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 traveling.

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 viewing over a long period, the recommendation is generally a maximum magnification of 10x. Larger magnifications make it more difficult 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 light. 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.) Calculating 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.

BAK4-PRISM
A prism is a complex optical component. It provides an upright image and allows compact binocular designs. Since the light beams in a prism are reflected several times at different angles the quality of the optical glass that makes up the prism is of crucial importance. PENTAX use prisms in WefdcfUhb[high purity BaK4 glass with a high refractive index.
