Abstract
Aspects are generally directed to a compact anamorphic objective lens assembly. In one example, the objective lens assembly includes a first anamorphic lens group including a first cylindrical lens having a surface optically powered in a first dimension and a second cylindrical lens having a surface optically powered in a second dimension orthogonal to the first dimension, the first anamorphic lens group being positioned to receive visible light along an optical path, a second anamorphic lens group positioned along the optical path to receive the visible light from the first anamorphic lens group, the second anamorphic lens group including a third cylindrical lens having a surface optically powered in the first dimension and a fourth cylindrical lens having a surface optically powered in the second dimension, and an aperture stop centered along the optical path and interposed between the first and second anamorphic lens groups.
