  • Optical system for forming an image on a concave spherical surface
    Patent number: 9146384
    Abstract: The invention relates to an optical system for forming and image on a concave spherical surface comprising, perpendicularly to the optical axis of the spherical surface, starting from the object side: a first elliptical plano-complex lens (L1) with convexity direct towards the object side; a second aspherical plano-concave lense (L2) whose radius of curvature decreases with distance from the axis, with concavity directed towards the image side, made of a material with a smaller Abbe number that that of the first lens; a parallel-faced plate (S1) on which bear the planer faces of the first and second lenses; a third aspherical plano-convex/concave lens (L3) exhibiting a convex shape in its central part and a concave shape at its periphery.
