Do you know the difference between roof prism and Porro binoculars? If not, don’t worry – you’re not alone. Many people are confused about the differences between these two types of binoculars. In this blog post, we will discuss the key differences between Roof prism vs Porro prism binoculars. We will also provide some tips for choosing the right type of binoculars for your needs.
How Do Prisms Work in Binoculars?
To understand the difference between roof prism and porro binoculars, it is helpful to first understand how prisms work in binoculars. Prisms are used in binoculars to direct the light that enters the binoculars into the user’s eyes. This is necessary because the lenses in the binoculars cause the light to bend (or refract). The prisms are used to “straighten out” the light so that it can be directed into the user’s eyes.

Two types of prisms can be used in binoculars: roof prisms and Porro prisms. Roof prisms are typically found in more modern binocular designs, while Porro prisms are typically found in more traditional binocular designs.

So, what’s the difference between these two types of prisms?
Porro Prism Binoculars
Porro prism binoculars are the most common type of binoculars. They are named after their inventor, Ignazio Porro, and typically have a rectangular shape. Porro prism binoculars use two prisms in each barrel to reflect and direct the light to your eyes.
This design results in a wider field of view than roof prism binoculars and makes them easier to hold steady. Porro prism binoculars are also typically less expensive than roof prism binoculars.
How Do Porro Prisms Work?
Porro prisms work by having the light reflect off of two mirrors that are perpendicular to each other. They are the traditional type of prism used in binoculars. This causes the light to be split into two beams, which are then recombined to form the image.

The prisms work by bending the light that comes into the binoculars so that the left and right images line up perfectly on your retina. This results in a three-dimensional image that appears natural to your brain.

Benefits of Porro Prism Binoculars
Porro prism binoculars offer a few key benefits that roof prism binoculars do not.
- First, the lenses are offset from one another, which creates a more spacious viewing experience. This is because the eyepieces are at the edges of the binoculars rather than in the center. This also gives Porro prism binoculars a wider field of view.
- Additionally, because the lenses are offset, light passes through more air, which reduces glare and improves image clarity.
Drawbacks of Porro Prism Binoculars
While Porro prism binoculars offer several benefits over their roof prism counterparts, they also have a few drawbacks.
- First, they are typically larger and bulkier than roof prism binoculars. This is because the lenses are offset from one another, which takes up more space.
- Additionally, Porro prism binoculars are not as compact as roof prism binoculars and can be more difficult to transport.
- They also require more maintenance because the prisms can become misaligned.
- Lastly, lens misalignment can lead to image distortion.
Roof Prisms Binoculars
There are many different types of binoculars on the market, and each has its own set of advantages and disadvantages. One type of binocular that is gaining in popularity is the roof prism binocular.
How do Roof Prisms Work?
The main difference between roof prisms and Porro prisms is how the light travels through the binocular. In a roof prism binocular, the eyepieces are in line with the objectives (lenses at the front of the binocular).
This means that the light path goes straight through the binocular without being reflected. Roof prism designs are usually more compact than Porro prism designs, but they cost more to manufacture.
Benefits of Roof Prism Binoculars
Roof prism binoculars have several advantages over other types, including Porro prism binoculars.
- Sleeker, more compact design than Porro prism binoculars. This makes them easier to carry around, and they take up less space in your backpack or luggage.
- Better light transmission thanks to coated optics. They also usually have better optics, providing a clearer image.
- Greater durability thanks to sealed construction. Another benefit of roof prism binoculars is that they’re often more durable than their Porro counterparts. Because the prisms are aligned in a straight line, there are fewer moving parts inside the binoculars, which means they’re less likely to break if you drop them.
- Reduced image distortion.
Drawbacks of Roof Prism Binoculars
Disadvantages of Roof Prism Binoculars:
- Roof prism binoculars are typically more expensive than Porro prism binoculars
Porro Prism vs Roof Prism
If you’re thinking about getting new binoculars, make sure to do some research on what type of lens system will work best for your needs. A Porro prism is great if you want a wide field of view while a Roof prism works better if you need high magnification power.
Roof prisms are typically lighter and more compact than Porro prisms.
[wpsm_box type=”info” float=”none” text_align=”left”]
This is because roof prisms are aligned in a straight line, while Porro prisms are offset from each other.
[/wpsm_box]
Roof prism binoculars are typically more expensive than Porro prism binoculars because they require more precise alignment during manufacturing.
Porro prism binoculars are typically heavier and bulkier than roof prism binoculars. However, they offer some advantages over roof prism binoculars. Porro prism binoculars tend to provide a wider field of view and greater depth perception than roof prism binoculars. They also tend to be less expensive than roof prism binoculars.
Eyepiece distance
Eyepiece distance is the distance between the eyepieces and the objective lens. This distance is typically measured in millimeters. Eyepiece distance can affect image quality, especially if it is too short or too long.
Porro prism binoculars typically have a longer eyepiece distance than roof prism binoculars. This is because the two prisms in a Porro prism are offset from each other, while the two prisms in a roof prism are aligned in a straight line. This difference in construction can cause problems with image quality if the eyepiece distance is too short.
Roof prism binoculars typically have a shorter eyepiece distance than Porro prism binoculars.
Price
Roof prisms are usually more expensive, but they offer some benefits in terms of image quality and compactness. Porro prisms tend to be less expensive, but they offer a wider field of view and greater depth perception. Ultimately, the decision comes down to personal preference and your specific needs. Whichever type you choose, we’re sure you’ll enjoy exploring the world around you in a whole new way!
Hybrid designs
Some hybrid designs use both Roof and Porro prisms. These usually have one Roof prism near the eyepiece and one or more Porro prisms further back in the optical path. This can provide the benefits of both designs in a single binocular. However, these binoculars are usually more expensive than either Roof or Porro prism binoculars.
Which Is Best to Use?
So, which type of prism is best? That depends on your needs and preferences. If you want a compact binocular, then a roof prism design is probably your best option. If you’re looking for the best image quality, then a Porro prism binocular might be a better choice.
And if you want the benefits of both designs, then a hybrid binocular might be the right choice for you. No matter which type of prism you choose, make sure to do your research and pick the best binocular for your needs!
Is image in Porro very different from roof binoculars?
There are a few key differences between roof prism and Porro binoculars. The most noticeable difference is that the image in porro is typically inverted, while the image in Roof prism is not. Roof prism binoculars are also typically more compact and have a narrower field of view than Porro binoculars.
[wpsm_box type=”info” float=”none” text_align=”left”]
Roof prism binoculars tend to have better optical quality, as the light path is shorter and more direct. This means that there’s less chance of image degradation.

Tips for choosing
If you’re looking for a quality pair of binoculars and don’t mind the slightly increased size, Porro prism binoculars are a great option. If compactness is key, then roof prism binoculars are probably a better choice. Whichever type of binocular you choose, always make sure to test them out before buying – especially if you plan on using them for bird watching or hunting.
