TELESCOPIC GRADIENT LENS Russian patent published in 1998 - IPC

Abstract RU 2114451 C1

FIELD: optical instruments. SUBSTANCE: device is made from material with radial gradient of refraction index n(y). Its ray path period length is L. Equation of ray path in lens material is V₁(Z). First front surface is flat. Second surface is convex which generatrix depends on above-mentioned equation. EFFECT: design of telescopic gradient lens which magnification is not equal to +-1, decreased lens thickness. 2 dwg
