Abstract
A two-surface narrow field-of-view (FOV) compound lens for producing an image of an object at an image plane of an imaging system includes a biplanar substrate between a plano-convex lens and a plano-concave lens having a common optical axis. The plano-convex lens has a first planar surface on a first side of the biplanar substrate and is formed of a material having a first Abbe number. The plano-concave lens has a second planar surface on a second side of the biplanar substrate opposite the first side, and is formed of a material having a second Abbe number less than the first Abbe number. The first and second lens have respective focal lengths F1 and F2 that may satisfy −1.4<F2/F1 <−0.9. The compound lens may have a total track length T and an effective focal length fsuch that their ratio satisfies 0.88<T/f<0.98.
