Do you want to go on an adventure but need the perfect apparatus to assist you with viewing objects from a distance? In this article we give you the lowdown on binoculars, supporting all outdoor activity enthusiasts.
Binoculars are essentially two telescopes mounted together on a single frame, to provide a magnified stereoscopic view of distant objects. Binoculars use curved lenses shaped like a dome, which refracts light, giving the viewer a 3-dimensional image. To create the 3-dimensional image convex and concave lenses are used simultaneously.
Some parts of the binocular were invented as early as the 12th century. Roger Bacon developed the first magnifying glass in 1250 which uses the same concept for the lenses used in binoculars. He wrote about how short-sightedness could be solved by using an object to magnify an item or newspaper when reading. After the fact, craftsmen would cut thin pieces of glass, setting them into frames so that people could wear them over their eyes thus leading to the invention of spectacles.
The concept of the binocular was invented by a man named Hans Lippershey in 1608 who created the convex and concave lenses. He was asked to use his invention to create two telescopes and put them side by side. Hans did this but his invention was rejected as the lenses had poor magnification.
The binocular went on to be perfected by an inventor named Ignazio Porro who created a prism system. A prism is a transparent piece of glass in the shape of a triangle refracting surfaces at an acute angle. This gives an image twice the magnification, as the two angles separate light into a range of color. Without this prism binoculars wouldn’t have been as popular, as they would be of sub-standard quality.
A year after Hans Lippershey’s invention, Galileo Galilei, an Italian scientist went on to introduce the telescope to astronomy. With his invention, he was able to magnify up to 30 times enabling him to view objects as far as the moon. His invention is still in use to this day.
All the parts and inventions mentioned above are used in manufacturing modern binocular technology. Today we’re able to use binoculars for several activities such as bird watching, opera, theater productions, hunting, military, and marine use.
