Distance between two distinguishable radiating points
- Resolution depends on the distance between two distinguishable radiating points. A microscopic imaging system may have many individual components, including a lens and recording and display components. Each of these contributes to the optical resolution of the system, as will the environment in which the imaging is performed.

Dec 24, 2022 · Key Points. Magnification is the ability to make small objects seem larger, such as making a microscopic organism visible. Resolution is the ability to distinguish two objects from each other. Light microscopy has limits to both its resolution and its magnification.
Jan 19, 2023 · In microscopy, the term “resolution” is used to describe the ability of a microscope to distinguish details of a specimen or sample. In other words, the minimum distance between 2 distinct points of a specimen where they can still be seen by the observer or microscope camera as separate entities.
Resolution is the ability to distinguish between two separate points. If two separate points cannot be resolved, they will be observed as one point. The resolution of a light microscope is limited by the wavelength of light. As light passes through the specimen, it will be diffracted.
May 26, 2021 · Resolution is the ability of the lenses to distinguish between two adjacent objects as distinct and separate. A compound light microscope has a maximum resolution of 0.2 µm, this means it can distinguish between two points ≥ 0.2 µm, any objects closer than 0.2um will be seen as 1 object.

The resolution of an optical microscope is defined as the shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities. An example of this important concept is presented in the figure below (Figure 1), where point sources of light from a specimen appear as Airy diffraction ...
Resolution is a somewhat subjective value in optical microscopy because at high magnification, an image may appear unsharp but still be resolved to the maximum ability of the objective. Numerical aperture determines the resolving power of an objective, but the total resolution of the entire microscope optical train is also dependent upon the numeri...
Correct alignment of the microscope optical system is also of paramount importance to ensure maximum resolution. The substage condenser must be matched to the objective with respect to numerical aperture and adjustment of the aperture iris diaphragm for accurate light cone formation and specimen illumination. The wavelength spectrum of light used t...
When the microscope is in perfect alignment and has the objectives appropriately matched with the substage condenser, then we can substitute the numerical aperture of the objective into equations (1) and (2), with the added result that equation (3) reduces to equation (2). An important fact to note is that magnification does not appear as a factor ...
The resolving power of a microscope is the most important feature of the optical system and influences the ability to distinguish between fine details of a particular specimen. As discussed above, the primary factor in determining resolution is the objective numerical aperture, but resolution is also dependent upon the type of specimen, coherence o...
Resolution is the ability of the lenses to distinguish between two adjacent objects as distinct and separate. A compound light microscope has a maximum resolution of 0.2 µm, this means it can distinguish between two points ≥ 0.2 µm, any objects closer than 0.2um will be seen as 1 object.
Microscope resolution is the amount of detail that can be resolved from the light being refracted through a specimen and presented to the observer through a microscope. Resolution can also be thought of as the minimum distance between two distinct points that can be distinguished by the observer.
