In this blog, we will explore roof prism binoculars and Porro prism binoculars, highlighting the key distinctions between the two.

What are Roof Prism Binoculars?

Roof prism binoculars are straight in the construction of the light path, which is the reason that they acquired the name. In these high-end binoculars, the prisms are aligned parallel to the objective and eyepiece lenses. This gives rise to a thin, upright structure that has gained popularity in recent years. Some of the advantages of roof prism binoculars are as follows:

2- Usually more rugged and waterproof

3- They are lighter and more stable in the hand

4- Special coatings are essential for optimal results.

What are Porro Prism Binoculars?

Porro prism binoculars, named after the Italian optician Ignazio Porro who invented this system of prisms, are arranged in an offset manner. The objective lenses are positioned wider than the eyepieces, creating a characteristic zig-zag light path that defines the shape of these lenses. Some of the key characteristics of porro prism binoculars include the following;

1- A classical and broader design

2- Usually provides better depth without compromising the field of view.

3- They have better light transmission which provides brighter images.

4- Additionally, the binoculars have a centre focus wheel which creates more 3D effect.
