Pretty much every feature to do with optics are linked to other features in some way. It sounds pretty complicated but once you get your head around it, it all becomes clear.

FoV at 1,000 yards is the linear measurement of the Field of View, it is usually expressed as either feet per 1,000 yards or as the angular measurement in degrees. So 315 feet at 1,000 yards means that you can see a field of view of 315 feet wide at a distance of 1,000 yards.

Definition ofopticsin Physics

The field of view is stated by the manufacturers in a couple of ways. Binoculars, spotting scopes and rangefinders measure the FoV in metres per 1,000 metres, but rifle scopes are measured in feet per 100 yards. Binocular manufacturers either use metres per 1,000 metres or as a degree.

If you see angular FoV on the description followed by something like 6° that means you can see 6 degrees width through the lenses. The higher the angle quoted depicts a wider field of view. To convert the degrees into metres per 1,000 metres just multiply the number of degrees by 17.5. This is because 1° is equal to roughly 17.5 metres. So to convert 8° into metres per 1,000 metres just multiply by that amount to calculate the linear FoV.

There is a direct relationship between the FoV and the level of magnification. It works like this, the higher the magnification, the lower the FoV. It’s fairly obvious when you think about it, as you close in on the object, you lose a great deal of the surrounding features.

20231019 — From compact cameras to DSLRs, each camera type offers unique advantages and benefits. Let's delve into the world of cameras and explore the different options.

In a nutshell the field of view (FoV) is what you can see through the lens from edge to edge. So that’s everything you can see through the lens from left to right and everywhere in between. But as with most things, there’s more to it than that. There’s the eyepiece, position of the lenses, how thick they are, the way they’re assembled and the magnification, all contribute to how the FoV comes together. So let’s get into the FoV of binoculars.

Put simply, eye relief is the correct distance between your eyes and the eyepiece. Having the correct eye relief will allow you to see the whole image and the full FoV. It is always given by the binocular manufacturer and the best eye relief is somewhere between 14 to 18mm.

Although the study of light has been underway for centuries, it is only in the last 40 years that optics and photonics has become a dominant field, with impact in almost every aspect of our lives, from entertainment, to medicine, to defense, to communications. In the 20th century, electronics was the dominant influencing technology, enabled by optics. The 21st century is the “Age of Light”, a century that will have optics and photonics as the dominant influencing technology, enabled in some cases by electronics.

Types ofoptics

It’s all about your positioning really, if you are too close to, or too far away from the eyepiece, your FoV will be affected. You might see the FoV slightly shaded or shadowed, or “clipped” this is called vignetting. So to get a clear image and to see the full FoV, you need to have the correct eye relief.

When manufacturers quote the linear FoV they are referring to metres per 1,000 metres, like 131 metres per 1,000 metres – it means that at 1,000 metres distance you can see 131 metres from side to side.
