The 7 is the magnification produced - it is a ratio of the focal lengths of the lens at the eyepiece and the front (objective) lens.
The 50 is width of the objective lens - in millimetres.

∙ 14y agoThe first number (16) is the "magnification" or "power" of the equipment, often described as how many "times closer"
it "makes things look". All of these terms are rather sloppy descriptions, but they convey the idea.
The second number (50) is the diameter in millimeters of the main big lens at the front of each side of the
binoculars, which is related to the light-gathering power, and thus to how bright the image will be
when you get done spreading it out 16 times more thinly than normal.

Are infrared binoculars available to the general public?
Infrared binoculars are available to the general public but are generally more expensive than conventional binoculars. The cheapest go for about $75 and can be as expensive as $600.
How apart from magnification do binoculars help you see better?
Yes they do. The important feature is diameter of the front lenses, these collect more light than you can get in through the unaided pupil of your eye. Therefore binoculars gather more information about what you are looking at than your eye can and you can see things with them that the unaided eye can not see. To test this go out on a clear night and point your binoculars at the sky, they will show you stars that you can not see without them. However, this light gathering power means you MUST NEVER try and look at the Sun though binoculars, if yo do so you will immediately be blinded.
Why are binoculars shorter than telescopes?
Binoculars are shorter than telescopes because of the prism located in them that shorten the length of the light waves. The lens in the tubes of the binoculars allows for the magnification of the objects seen in the distance.
What do the numbers mean on a telescope?
Example: 7 x 507 = Magnification.The image appears 7 times bigger through the binocs than it appears to the naked eye,giving the illusion that it's nearer.50 = the size of the main lensat the front of each side, 50 millimeters in diameter. The larger that lens is, the brighterthe image appears.
How do you calculate distance with the use of binoculars?
Just go outside on a clear night and point the binoculars in the direction of stars and start looking. Then you can start to scan around and see what you can see. The longer you are outside, the more time your eyes have to adjust to the darkness and you should see better. If you can be somewhere where there are few or no street lights, you will see more than if you are in a large town.

What is the most powerfull binocullers?
Binocular telescopes, with interchangeable eyepieces, can have a focal length as long as you like. Generally, any binoculars that advertise based on the magnification will be useless, as the picture quality will be unbearable. Also, binoculars with more than 15x can be hard to hold. It is better to get a good pair of 8 or 10 x binoculars with a larger front element. If you really want though, it does not get much more powerful than this: http://www.overstock.com/Sports-Toys/Full-Size-Zoom-Binoculars/2866058/product.html 120x

Why aren't all galaxies visable through binoculars?
Some are very close to earth, and others are much farther away. This is why only some ranges of binoculars can see farther into the night sky than other, ordinary, binoculars.
How much are W.W.2 military issue binoculars worth?

Does binocular use lens?
Yes, binoculars use similar lenses to telescopes but with a system of prisms to fold the light path to permit binoculars to be much shorter than a regular telescope.

What these are used for binoculars?
Binoculars are distinguished from telescopes through the use of "folded optics". That is, the light path is folded into the body, allowing a compact design. Rather than mirrors, prisms are used to reflect the light.
How can spotting scope make our outdoors fun?
If you are hunting a spotting scope is very useful. On the other hand if you are just bird watching or enjoying the sites it can also be nice to have, they tend to be better than binoculars and lighter as well.

How are your eyes similar to a telescope and how are they different?
Your eyes are actually much more similar to binoculars than they are to a telescope, in that binoculars give one stereoscopic vision, like the human eyes do. But all binoculars magnify, and many have zoom magnification - the human eyes adjusts only for "basically close" and "basically far away".
