Rayleigh criterion for diffraction limited resolution through a circular aperture YouTube Start of suggested clip End of suggested clip Aperture. Note that a larger value of the wavelength. Results in worse angular resolution so theMoreAperture. Note that a larger value of the wavelength. Results in worse angular resolution so the minimum resolvable angle becomes larger if lambda is larger meaning you're not going to resolve.

In order to increase the resolution, d = ?/(2NA), the specimen must be viewed using either a shorter wavelength (?) of light or through an imaging medium with a relatively high refractive index or with optical components which have a high NA (or, indeed, a combination of all of these factors).

The factor of 1.22 applies to circular apertures like the pupil of your eye or the apertures in telescopes and cameras. When light passes through an aperture with diameter D, then diffraction limits the resolution to ? = 1.22?/D. If the angular separation of two sources is less than ?, they cannot be resolved.

The resolution limit of a microscope is the shortest distance between two nearby objects when the images formed by the microscope are properly differentiated. The resolving power of the microscope is Xmin = 1.22?/ numerical aperture.

Microscope Resolution Equation Here is one equation we use: (r) = 0.61? / NA, where r is resolution, ? is the imaging wavelength (550nm on average), and NA is the numeric aperture of the objective lens in question.

Definition 2: Resolution can be expressed as the total number of pixels. With megapixel cameras, the resolution is generally the total number of pixels, divided by 1,000,000, and rounded off.

Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 ? (where ? is the standard deviation) and the peak FWHM is W0.
