Can Fermat`s Principle accurately predict lens focusing? - TEM-EELS
... The focusing power can be deduced much more quickly and with apparently no approximation by using Fermat’s Principle, according to which the time taken by light to travel between any two points is the smallest possible value. This least-time principle implies that if light can take two of more paths ...

... To break a beam of light into a spectrum, one separates the wavelengths of light by passing the light through either a grating or a prism. But, before the light passes through the grating or prism, it should first pass through a narrow slit. Then, the light that passes through the grating or prism i ...
