early 15c., from Late Latin magnificationem (nominative magnificatio), noun of action from past participle stem of magnificare (see magnify).

Enlargement in the size of an optical image. For telescopes, magnification is not as important as the ability to gather light, which depends on the diameter of the primary lens or mirror.

The process of enlarging something in appearance, not in physical size.

Enlargement in the size of an optical image. For telescopes, magnification is not as important as the ability to gather light, which depends on the diameter of the primary lens or mirror.

The amount that a telescope enlarges its subject. It’s equal to the telescope’s focal length divided by the eyepiece’s focal length.

Two kinds of magnification are useful to describe optical systems and they must not be confused, since they aren't synonymous. Any optical system that produces a real image from a real object is [..]

The ability to use a microscope to make an object look bigger.

The apparent enlargement of an object by an optical instrument.

The ratio of the image distance to the object distance; the ratio of the image size to the object size.

(Aka power) magnification is how much larger an object appear when view through a scope or binoculars than it would appear to the naked eye.

The first number in a binocular’s rating (i.e. 10x). Magnification is calculated by dividing the focal length ratio of the eyepiece by focal length ratio of the objective lens. As an example, a magnification of 10x makes an object appear ten times closer. For binoculars, the most common magnification levels fall between 8x and 12x.

The magnification of a lens compared to the naked eye. A 10x magnification will make the distant subject appear 10x bigger than it is. A common mistake that many binoculars buyers make is to rush out [..]

In microscopes, to make something larger in size by use of lenses. Total magnification is determined by multiplying the magnification of the eyepiece lens by that of the objective lens. (For example, eyepiece 10x and objective 40x= 400 times magnification.)

Number of times image is larger than subject. Thus a magnification of 2 indicates the image is twice life-size, while a magnification of 0.5 indicates the image is half life-size.

Multiply the magnification of the eyepiece by the magnification the objective lens for the total magnification at that power. 400x or 1000x is necessary for studying cells and cell structure. Top

Also called power, it’s the first number listed in basic binocular specs, e.g. 8×42, An 8X or 8- power binocular will magnify the image 8 times, so an object that’s 800 feet away will appear as if it were only 100 feet away.

Optical and imaging magnification is a ratio of image angular subtense to object angular subtense. Electronic, or linear, magnification is the ratio of monitor size to sensor size. For example, 13&quo [..]

Use of optic and geometric techniques to enhance radiographic image quality and interpretation. It includes use of microfocal X-ray tubes and intensifying fluoroscopic screens.

Relationship of the length of a line in the object plane to the length of the same line in the focal plane. It may be expressed as image magnification (image size/object size).

increasing the apparent size of (an object) using a lens or lenses; also refers to increasing concentration of certain chemicals as they pass through a food chain (see biological magnification)

A speaker’s selecting and emphasizing certain qualities of a subject to stress the values they represent.

The apparent enlargement of anything.

Enlargement in the size of an optical image. For telescopes, magnification is not as important as the ability to gather light, which depends on the diameter of the primary lens or mirror.

the increase of an object's apparent size by using lenses or mirrors
