In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has the property that it is constant for a beam as it goes from one material to another, provided there is no refractive power at the interface. The exact definition of th…

"WebCrown glasses are optical glasses with low chromatic aberration (Abbe number above 55 or 50) which tend to have low refractive index. Many optical components such as lenses, mirror substrates, optical windows, and prisms are made from crown glasses. They are particularly useful for imaging applications as they minimize chromatic aberrations. " - Optic total lens
