Roof Prism vs. Porro Prism Binoculars
Binoculars work on two main principles: magnification and image re-orientation. A simple magnifying lens (the objective lens) magnifies the image, and a prism orients it the right way up. A roof prism binocular has two prisms stuck together such that the light passes through in a straight line. In a Porro prism, however, the prisms are slightly offset, bending the light slightly.
Porro prisms (Porro meaning the name of its inventor), while they may seem bulky and weighty, provide better image quality. They enhance the image better and provide a wider field of view. This may not be necessary for you if you’re just finding your way across the sea or observing.
But for birdwatchers and stargazers, catching even the tiniest glimpses is extremely crucial. Porro binoculars are highly recommended for their wider field of view, which makes hunting a breeze.
Roof prism binoculars have less clarity, but they’re compact. So if the size is a problem for you, then go for roof prism binoculars. They’re also better at waterproofing.
Porro binoculars are good for everything except long-range spotting. But roof prism binoculars are only good for long-range spotting and daytime hunting. Otherwise, the image clarity just isn’t worth it.
One thing to consider is that, despite their modernity, Porro prism binoculars are cheaper than roof prism binoculars.
FAQ
What is a Porro prism binocular?
A Porro prism binocular is one in which the two prisms are slightly offset to each other. This results in a wider field of view. These binoculars are great for hunting and short-range birding.
Which is better: roof prism or Porro prism?
Making the Porro vs roof comparison is quite hard. Porro prism has a jog in the light path, whereas the light goes straight through in the Roof prism.
Roof prisms cost more to make. Porro prisms are better at light transmission and show better contrast. They are good for almost everything except long-range spotting. They’re not as durable as roof prisms.
How do Porro prisms work?
Porro prisms work by first magnifying the image and then inverting it using two prisms. The prisms are offset, so the light ray has to make a short horizontal movement. This makes the image wider and opens up your field of view.
