Examples of 'numerical aperture' in a sentence
Meaning of "numerical aperture"
Numerical aperture refers to the measure of the acceptance angle of an optical system. It is a characteristic of optical systems, such as lenses, that determines the amount of light that can enter the system. The numerical aperture is typically denoted by the symbol 'NA' and is used to calculate the resolving power and light gathering ability of an optical system
