The lens maker’s formula involves the focal length, refractive index of the material of the lens and the radius of curvature of the two surfaces of the lens. This formula is derived from the refraction of light on the two spherical surfaces of a lens. In Fig. refraction of light at the...
The Dioptre formula is used to calculate the optical power of a lens or curved mirror. The dioptre is the unit for a measure of the refractive index of a lens. The power of a lens is specified as the inverse of the focal length in meters, or D =1/ f, where D is the power in ...
The secondary focal length of a thin lens in air is given implicitly by the lens-maker's formula, (2)1f'=(n−1)(1R1−1R2), where R1 is the radius of curvature of the first surface and R2, of the second, and where radii of curvature are measured from the surface, so the ...

"One lensmaker who is marching in the opposite direction from HDR is Les Zellan, chairman of U.K.-based Cooke Lenses. Where the latest cameras may tout high resolution and high contrast, Zellan says that Cooke has struck the right balance of resolution and contrast “to give the picture ...

The "thin" part of a thin lens is an approximation that ignores almost all of the lens' properties aside from its focal length. A more general treatment of the lens can be found in other lens-related equations like the Lensma...
