Powerful Binoculars 2021 for Adults
What is the difference between a binocular and a telescope?
The difference between a binocular and a telescope is that they have a wider field of view and less magnification than the telescope. Light penetrates through the lens and focuses the image seen in our eyes. The prisms allow the image to be seen correctly in our eyes, since it comes from more distant axes.
The binocular was first conceived in 1608, when Hans Lippershey attached two telescopic tubes to observe objects at great distances, seeking a clearer image with it. But this origin is still questioned, since many claim that it was not an invention but an experiment. In the 17th century, the German priest Reitha attached 2 telescopes to what he called binoculars.
The creation of the first model itself, like the ones we use today, was developed by D'Orleans de Cherubin from Milan and by I.M. Doubler from Berlin, during the first half of the 18th century. They were not well received by the public, prompting the inventors to abandon the project entirely.
In 1854, the Italian inventor Ignatio Porro integrated a prism into the box of the most advanced binocular designs. It became very popular due to this invention, and Porro's prism ended up being named in a tribute after his death.
The main feature of the Porro prism is that it allows the condensation of light from the light source to enlarge the images seen from the exit pupil, becoming the basis of today's functional binoculars.

This equipment is suitable for terrestrial, maritime and, in some cases, astronomical observation.
