I was given this equation:
##\frac{1}{\lambda f} e^{ikr^2f}##,
where ##\lambda## is the wavelength of light and ##f## is the focal length of the lens. I was told that it is called the "lens phase", but I have no luck in finding it using Google.
I suppose this is multiplied when a beam of light travels through a lens.
