Magnification and Resolving Power - The Student Room
Spirogyra alga. We are at the limit of resolution for this objective. Further magnification of the image will not reveal more details. The only possibility to increase. Not to be confused with magnification, microscope resolution is the shortest distance between two separate points in a microscope's field of view that can still be. They do this by making things appear bigger (magnifying them) and at the same time increasing the amount of detail we can see (increasing.
This is due to the irregularity and abnormality in the design of lenses used in optical instruments.
Numerical aperture and resolution | greenfluorescentblog
When two objects that are held apart and at a distance from the viewer are magnified many times, they will have edges that become blurry, and it becomes impossible to see two separate objects. To achieve a high magnification and resolution at the same time, a combination of ocular and objective lenses are used with numerical aperture or light range angles that are different. The wavelength by which light hits the object will also affect its resolution; the lower it is, the higher the resolution.
Magnification is the ability of optical instruments, such as a telescope or a microscope, to make an object bigger while resolution is the ability of optical instruments to produce images that are clearer, finer, and sharper.
Resolution is the power of an optical instrument to capture and produce more details of an image while magnification is the power of an instrument to create and produce a much larger image of an object. Although both are dependent upon each other, a high magnification does not always guarantee a high resolution. 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 with more details.

Please spread the word. Further magnification of the image will not reveal more details.
The only possibility to increase resolution is to switch to an objective with a higher resolving power, to use a shorter wavelength of light or to generally improve the optics. But there is a physical limit. A part of the above image was further magnified 2x. No additional details become visible. You are in a shop and have a choice between two microscopes.
One is capable of magnifying x, the other one is capable of magnifying x. Which one is better? Given only this information, most people would opt for the x device.
Relationship between magnification and resolution in digital pathology systems
A larger number, in the mind of the uninitiated consumer, means a better quality and more value. Technical and scientific instruments and even consumer electronics, such as digital cameras, have become increasingly complex and the consumers often demand a quick and easy measure to compare the different instruments.
In the case of microscopes it is often the magnification, in the case of digital cameras it is the number of mega pixels, and computers are often compared using CPU speed and memory. Simple numbers, simple comparison. So a x microscope, in the mind of a lay person, will show you 4 times as much as a x device. This drive for large numbers is even visible in other optical devices, such as telescopes.
