Thin lens - Wikipedia
In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces. Lenses whose thickness is not negligible are sometimes called thick lenses. The thin lens approximation … See more The focal length, f, of a lens in air is given by the lensmaker's equation: $${\displaystyle {\frac {1}{f}}=(n-1)\left[{\frac {1}{R_{1}}}-{\frac {1}{R_{2}}}+{\frac {(n-1)d}{nR_{1}R_{2}}}\right],}$$ where n is the index of refraction of the lens material, and R1 and R2 are the radii of curvature of the … See more Certain rays follow simple rules when passing through a thin lens, in the paraxial ray approximation: • Any ray that enters parallel to the axis on one side of the lens … See more In scalar wave optics a lens is a part which shifts the phase of the wave-front.
