Difference between Resolution and Magnification

Difference between resolution and magnificationResolution and magnification are two terms used in Optics which are related to each other. The Basic difference between resolution and magnification is that Resolution is the ability to separate two closely placed objects while magnification is the mean of increasing the size of the object.

Resolution Vs Magnification



1.Resolution is the capacity to separate adjacent objects.1.Magnification is the means of increasing the size of the object.
2.Resolution is maintained up to a certain magnification.2.By increasing magnification resolution is disturbed.
3.Resolution improves as

The wavelength of illumination becomes shorter.

3.Magnification improves

With the focal length of the lens

Optical instruments are used to enhance images, analyze light waves, and determine the characteristics and properties of a subject. There are various optical instruments that have been created, such as; Camera, photometer, reflectometer, refractometer, autocollimator, and spectrometer, to name a few.

However, the oldest and most common optical instruments are the microscope and the telescope. The microscope is used for small image magnification and the telescope for magnifying images from far away.

When viewing these images, it is important that they also have a good resolution. Resolution is the fineness, sharpness, and clarity of the image produced when viewed through an optical instrument. It is the ability of the instrument to produce a detailed image of a subject. It captures more detail that we can see even if the image is enlarged, and can produce an image that can be examined more closely and more clearly. Resolution can be expressed in seconds or seconds.

What is magnification?

Magnification, on the other hand, is the degree to which an object becomes larger using optical instruments such as a telescope or a microscope. They bend the light to magnify an image to the point where the magnification becomes indistinguishable. It can be expressed with an integer and a letter “X”.

Magnification and resolution are interdependent on each other. But while high magnification generally means high resolution, many times, the larger an image becomes, the lower its resolution, since as the image doubles, so is its area. This is due to the irregularity and abnormality in the design of lenses used in optical instruments. When the two objects that are kept apart and away from the viewer are enlarged many times, they will have edges that become blurred and it is impossible to see two separate objects.

To achieve high magnification and resolution at the same time, a combination of objective and ocular lenses with numerical aperture or different light range angles is used. The wavelength at which light strikes the object will also affect its resolution; The lower it is, the higher the resolution.


1. Resolution is the ability of optical instruments to produce clearer, finer, and sharper images, while Magnification is the ability of optical instruments, such as a telescope or microscope, to enlarge an object.
2. Magnification is the power of an instrument to create and produce a much larger image of an object, while Resolution it is the power of an optical instrument to capture and produce more detail from an image.
3. The resolution can be expressed in seconds or seconds, while the magnification can be expressed with an integer and the letter “X”.
4. Although both depend on each other, a high magnification does not always guarantee a high resolution.
5. Magnification allows us to see small objects, especially those that are not visible to the naked eye, while resolution allows us to see these objects more clearly and in more detail.
