Patent ID: 11287618

Abstract:
The anamorphic objective lens systems (100LS) and methods for forming a set of anamorphic objective lens assemblies (100(i)) having different focal lengths (FLY) and that utilize a front anamorphic section (20) and a set of two or more non-anamorphic sections (50(i)). The non-anamorphic sections are optically matched to the front anamorphic section and their front ends (52) are configured to be easily attached to and detached from the back end (24) of the front anamorphic section to create the anamorphic objective lens assemblies having the different focal lengths. Because the anamorphic objective lens system uses only a single front anamorphic section and multiple non-anamorphic attachments, the cost of having multiple anamorphic objective lens assemblies is substantially reduced as compared to using individual anamorphic objective lenses for each of the desired focal lengths.
