The prims are in the shape of a right angled triangle and they reflect the light rays through the binoculars so you see your image clearly.
The light path refracts more light thereby allowing a brighter image and better optics to be visible.
As a result they cost more to make.
Therefore at the cheaper end of the market they can often outperform a roof prism of the same price because to save money the will use less layers or lower quality mirror coatings.
In roof binoculars prisms are arranged in a straight line which makes roof binoculars more compact and lightweight compared to porro binoculars.
But inside they had a more complex light path and required much greater optical precision in manufacturing.
Prism in roof binoculars doesn t reflect 100 of the light that enters its lenses.
Due to the path of light passage porro prism binoculars have bulkier wider design than roof prism binocular.
Porro prism binoculars are bigger and heavier in size than roof prism but it is very much popular in traditional days still in the modern era it is equally necessary.
The porro prism design was simpler and more light efficient and its images showed better contrast.
