Anamorphic lens system with lens mounting structures
A system may include first lens with a first optical component and a first mounting structure having a first wall on a first side and a second wall on second side, each wall having a gap. The system may further include a second lens that interlocks with the first lens. The second lens includes a second optical component and a second mounting structure that engages with the first mounting structure.
