Microscope Resolution: Concepts, Factors and Calculation
Jan 19, 2023 · Resolution is intrinsically linked to the numerical aperture (NA) of a microscope’s optical components, like the objective lens, as well as the wavelength of light used. This article covers some of the history behind resolution concepts and explains each one using relatively simple terminology.
Resolution - Nikon’s MicroscopyU
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.
Optical resolution - Wikipedia
Optical resolution describes the ability of an imaging system to resolve detail, in the object that is being imaged. An imaging system may have many individual components, including one or more lenses, and/or recording and display components.
How to Calculate Resolution of a Microscope: A Step-by-Step …
Mar 6, 2023 · When it comes to microscopy, the resolution is a crucial factor to determine the quality of an image. The resolution of a microscope is the ability to see two separate objects as distinct and separate from one another. In essence, the higher the resolution, the more detail one can perceive in an image.
Resolution and Numerical Aperture | Teledyne Vision Solutions
Resolution, the ability to tell two nearby features apart, is a key parameter of microscope optics that becomes more challenging at smaller length scales. Yet, this has surprisingly little to do with the microscope's ability to magnify. In this technical note, the underlying principles that define resolving power, and the conditions necessary ...
Microscope Resolution
Even though 200 nanometers is considered the optimal resolution for optical microscopes, higher resolutions can be obtained using fluorescence microscopy. When combined with a laser light source, focal plane resolution of 15-20 nanometers can be achieved.

One way of increasing the optical resolving power of the microscope is to use immersion liquids between the front lens of the objective and the cover slip. Most objectives in the magnification range between 60x and 100x (and higher) are designed for use with immersion oil.
Microscopy Resolution: Concepts, Factors, and Calculations
Jul 3, 2023 · In microscopy, the term ‘resolution’ is used to describe the ability of a microscope to distinguish fine details. In other words, this is the smallest distance between two physical points within the sample that can be distinguished by an observer or a microscope camera.
Numerical Aperture and Resolution - Olympus
The greatest resolving power in optical microscopy is realized with near-ultraviolet light, the shortest effective imaging wavelength. Near-ultraviolet light is followed by blue, then green, and finally red light in the ability to resolve specimen detail.
In digital microscopy, there are two primary settings that will determine your resolution: the optical resolution of the microscope and the digital resolution of your camera/detector. Optical Resolution is determined primarily by the objective numerical aperture (NA) and the wavelengths of light collected by the camera/detector.
