Abstract

The system consists of a converging meniscus lens (L1) with the convex side, and a diverging meniscus lens (L2) with the concave side facing the incident light. Also a concave spherical mirror with a bore in the centre and a convex mirror vapour-deposited on the back of the diverging meniscus lens. Finally, two corrective lenses (L3, L4) positioned in the bore of the concave spherical mirror. The first lens (L3) is concavo-convex or plano-convex, whilst the second lens (L4) is divergent. The radii (r) and the distances (e) deviate by max. (+-) 10%, refractive indices by max. (+-) 0.3 units and the Abbe GAMMA values by max. (+-) 10 units from the data provided.
