Magnification, or in some cases lack of magnification, is equal to the telescopes focal length divided by the eyepiece focal length. For example: Take a telescope with a 1220mm focal length. When a 32mm eyepiece is used, the total magnification would be 1220mm divided by 32mm or 38 power.
The degree to which the viewed object is enlarged. For example, with a 7x42 scope, the number 7 represents the scope's "power.” This scope would magnify an image by seven times. The level of magnification power affects the brightness of an image, so the lower the power of a magnifying optic, the brighter the image it will deliver. In general, increasing magnification power will reduce both field of view and eye relief.
In a telescope, an increase in the apparent size of an object. The process of magnification expands the apparent size of an object by spreading the image, or light, across a large area. A large primary mirror or objective lens of a telescope focuses incoming light toward an eyepiece lens that actually magnifies what the telescope sees.
Also called "Power", this number reflects how many times the image is magnified. For example, through a 10x binocular the image will appear 10 times larger than with an unaided eye, an 8x will magnify only 8 times.With 8x power, an object which is 800 feet away will appear as if it was only 100 feet away.
Riflescopes are often described by two numbers separated by an "x". For example: 4x40. The first number is the power or magnification of the scope. With a "4x", the object being viewed appears to be four times closer than when seen with the unaided eye.
A term used with regard to lenses and has evolved to be the same with “power” when describing the size of a zoom lens. A 16 to 160 mm lens is said to be a 10X or ten power zoom lens. It has a magnification of 10. The other standard is a 6X lens like a 12.5-75 mm. The largest mm is divided by the shortest mm to give the power or magnification.
The magnification of a binocular refers to how many times larger an object appears. For example, with a x10 magnification an object 1000 yards away would appear to be only 100 yards away. The most common magnification is 8x. Tips: The lower the magnification the wider the field of view is and the easier it is to hold a steady image. High magnification is useful for birding and star gazing but a wide, steady field of view is more useful for hunting and general use.
changing the size of a font by expanding, or contracting, the positions of the coordinates used to draw the lines which make up the characters. Unequal magnification will change the shape of the characters making them wider or narrower than the original.
Spotting scopes are often referred to by numbers separated by an "x". For example: 15–45x60. The first number is the power or magnification of the spotting scope. With a 15–45x60 variable power spotting scope, the object being viewed appears to be 15–45 times closer than you would see it with the unaided eye.
The focal length of the telescope divided by the focal length of the eyepiece. A 10-mm eyepiece in a telescope with a 900-mm focal length yields 90X magnification. The longer a telescope's focal length, the more magnification a given eyepiece will produce.
Optical magnification is a ratio of image angular subtense to object angular subtense. Electronic, or linear, magnification is the ratio of monitor size to CCD sensor size. (For example, 13" monitors are between 38 and 39 times as large as 1/2" size format CCD cameras when comparing horizontal, vertical, or diagonal measures.)
An increase in apparent size of an object or its image. magnification, relative size (linear) - increasing the physical size of an object for example, enlarged print, a large faced clock; magnification , relative distance - enlarging the retina image by bringing the object closer to the eye. Plus (convex) lenses are used to accommodate for the close working distance; magnification, angular - the increasing the angular substance of an object at the eye by using multiple lenses (e.g. a telescope).
The size of the image relative to the size of the subject used to produce it. It is an expression of the ratio of the subject-lens distance to the image-lens distance. When object distance = image distance, magnification = 1.
Magnification is the process of enlarging something only in appearance, not in physical size. Magnification is also a number describing by which factor an object was magnified. When this number is less than one it refers to a reduction in size, sometimes called minification.
Magnification is an album by progressive rock band Yes released in 2001. The band's first album of the new century, and their first with a full orchestra, Magnification has proven to be one of Yes's more acclaimed later efforts.
