Abstract:

In an objective lens system of the Double Gauss type, negative lens elements are symmetrically disposed on both sides adjacent the stop, each negative element being a cemented doublet comprising a double convex negative and a positive lens element. A cemented doublet positive lens component is next positioned at the outside of each of the negative elements and a single positive lens is positioned at the outside of each of the inner positive lens components.
