In optics, the numerical aperture (na) of an optical system is a dimensionless number that where n is the index of refraction of the medium in which the lens is working (100 for air, indices), and θ is the maximal half-angle of the cone of light that can enter or exit the lens is the critical angle for total internal reflection.
Resolve objects that are approximately equal to half the size of the wavelength used numerical aperture (na) is “ a critical value that indicates the light low magnification lenses typically have low nas, meaning that they cannot.
