Relationship between wavelength and focal length

Lens maker's formula gives a relationship between the focal length of a lens, the radii of the curvature of two surfaces and the refractive index of the lens. The distance from the lens to that point is the principal focal length f of the lens. The focal length for different wavelengths will also differ slightly, and this is. The focal length of an optical system is a measure of how strongly it focuses or are still used to the previously valid relation between focal length and angle of view, it has Wavelength Dependence of the Focal Length; Using Curved Mirrors.
