Microscopic Resolution

Microscopic Resolution Definition

The microscopic resolution also is known as resolving power. Resolution is defined as the ability of a lens to separate or distinguish between small objects that are close together or the ability to distinguish two adjacent points as distinct and separate.

Equation of Microscopic resolution

The microscopic resolution can be calculated by using Abbe Equation.  Resolution is described mathematically by an equation developed in the 1870s by Ernst Abbe, a German physicist responsible for much of the optical theory underlying microscope Design.

The Abbe equation is;

abbe equation


d =  Distance between two objects.

𝞴 = Wavelength of light.

nsin𝝧  = Numerical Aperture.

When d becomes smaller, the resolution increases, therefore the resolution (r );
