Based on structure, visibility and a whole lot of other specifications, binoculars are classified into two categories – Galilean Binoculars and Prism Binoculars. We’ll be discussing in detail what sets these binoculars apart, their features, other USP’s, subtypes and also, which one is better suited for what kind of usage. So read on, as we elaborate over the types of binoculars:
The Galilean binoculars have derived their name from the famous astrophysicist Galileo Galilee. The structure of the Galilean Binoculars is similar to that of the telescope used by Galileo for astronomical observation way back in 1609. The combination of convex and concave lenses is the main reason behind the erect and clear images provided by these binoculars. The Galilean Binoculars do not have the concept of prism in them, which makes these binoculars compact and easily foldable. However, the field view of these binoculars is restricted and won’t give you a peripheral view. The maximum magnification that can be expected out of these binoculars is up to 4x.
The only difference between the Galilean Binoculars and the Prism binoculars is that the prism binoculars use only convex lenses for the generation of images, unlike the Galilean Binoculars which include both convex and concave lenses. While the difference between these two may seem negligible, the use of only convex lenses in Prism Binoculars has made an immense difference in the view and magnification provided by these binoculars.
The Prism binoculars are further categorised into two:
Porro Prism Binoculars:
This pair of binoculars works on the mechanism of four strategically placed prisms, which are used to generate crystal clear images with a high magnification value. It was invented by Ignazio Porro, an Italian somewhere in the middle of the 19th century. The view provided by these binoculars is classic and top-notch, which is why this mechanism is most preferred and accepted around the world.
Roof Prism Binoculars:
Also known as Dach binoculars, these binoculars use a roof prism mechanism to ensure high-quality visibility and clear images. The word ‘Dach’ means ‘roof’ in German, which explains the Roof Prism mechanism well. Equipped with a prism with a roof-shaped surface, the simplicity of the mechanism in these binoculars makes it easy to use, light in weight and compact too. People around the world are flattered by the sleek structure of these binoculars. It is one of the most commonly used binoculars because it is considered to be the best binoculars for the money that is paid. Apart from this, these binoculars have impressive magnification and other facilities.…
