Consequently, the numerical aperture of the microscope objective has a much greater effect on axial resolution than does the emission wavelength. One equation commonly used to describe axial resolution for the confocal configuration is given below, with η representing the index of refraction, and the other variables as specified previously:

The numerical aperture of a microscope objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object (or specimen) distance. 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 numerical aperture can be expressed and determined by the following formula: Numerical Aperture (NA) = n • sin (α) In the above equation, ‘n’ is the refractive index of the medium between the cover glass and the front lens of the objective (for example; air, water or oil).

Numerical aperture: The numerical aperture of the lens typically increases with the magnification, starting at around 0.25 on a 10x lens, then 0.6 to 0.8 on a 20x lens, and 1.47 on an oil immersion lens. Magnification: The magnification we are referring to is only that of the objective lens and not the ocular lens.
