WebIn optics the Lagrange invariant is a measure of the light propagating through an optical system. It is defined by , where y and u are the marginal ray height and angle respectively, and ȳ and ū are the chief ray height and angle. n is the ambient refractive index. WebLCA is the result of dispersion of the chief ray. Thus, when a lens exhibits LCA, light is affected very similarly to light traveling through a dispersive prism (figure 1.5). Imagining the prism in figure 1.5 is the tip of a lens shows us how the phenomenon occurs in a lens like one from figure 1.4.

The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays: propagate in straight-line paths as they travel in a homogeneous medium.
