摘要

An F/1.27 objective lens suitable for night vision applications employing lanthanum axial gradient-index (GRIN) materials is described. Although two GRIN elements were used, the number of elements was not substantially reduced relative to that of conventional homogeneous systems with equivalent performance. Tolerances and fabrication issues are discussed.
