Limitations of Resolution The resolution of the light microscope cannot be small than the half of the wavelength of the visible light, which is 0.4-0.7 µm. When we can see green light (0.5 Aµm), the objects which are, at most, about 0.2 Aµm.

The resolution of an optical microscope is defined as the smallest distance between two points on a specimen that can still be distinguished as two separate entities.

The ocular lens is found in the eyepiece while the objective lens is found in the revolving nosepiece. The resolving power is the capacity of an instrument to resolve two points that are close together. The resolving power of a compound microscope is 0.2503bcm.

In order to increase the resolution (d=03bb/2 NA), the specimen must be viewed using either shorter wavelength (03bb) 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).

In microscopy, the term 'resolution' is used to describe the ability of a microscope to distinguish detail. In other words, this is the minimum distance at which two distinct points of a specimen can still be seen - either by the observer or the microscope camera - as separate entities.

Thus, according to the formula d = 0.61 03bb / NA, the resolving power can be increased in two ways:decreasing the wavelength, 03bb (ie by using filters)increasing the NA. As stated earlier, NA = n sinu. Thus, NA can be increased the following ways:

In order to increase the resolution (d=03bb/2 NA), the specimen must be viewed using either shorter wavelength (03bb) 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 resolution of a microscope or lens is the smallest distance by which two points can be separated and still be distinguished as separate objects. The smaller this value, the higher the resolving power of the microscope and the better the clarity and detail of the image.

Resolution is an important HPLC performance indicator usually assessed by how quickly and how completely target components in a sample separate as they pass through a column. Resolution is measured by dividing the difference in peak retention times by the average peak width.

Dmin= (1.22 03bb)/(2 sin 03b2) Therefore dmin= (1.2203bb)/ (2n sin03b2) is known as numerical aperture of the objective lens. Resolving Power(R.P) of a microscope 221d (1/dmin). This implies resolving power decreases as the distance increases.
