It is defined by :$H\; =\; n\backslash overliney\; -\; nu\backslash overline$, 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. In order to reduce confusion with other quantities, the symbol Ж may be used in place of H. ''Ж''2 is proportional to the throughput of the optical system (related to étendue).〔 For a given optical system, the Lagrange invariant is a constant throughout all space, that is, it is invariant upon refraction and transfer. The optical invariant is a generalization of the Lagrange invariant which is formed using the ray heights and angles of any two rays. For these rays, the optical invariant is a constant throughout all space.〔(Optics Fundamentals ), Newport Corporation, retrieved 9/8/2011〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lagrange invariant」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
