Anamorphic lens system with lens mounting structures

An anamorphic lens system comprising:

• a first lens comprising:
• a first optical component having a first optical surface with a curvature asymmetrical about an optical axis;
• and
• a first mounting structure configured to engage with a mounting structure of an adjacent lens, the first mounting structure having a first wall on a first side and a second wall on second side, each wall having a gap, the first wall and the second wall being opposite each other on the first mounting structure;
• and
• a second lens configured to interlock with the first lens, the second lens comprising:
• a second optical component having a second optical surface with a curvature asymmetrical about the optical axis;
• and
• a second mounting structure configured to engage with the first mounting structure, the second mounting structure having a first barrier with a first protrusion and a second barrier with a second protrusion, the first barrier and the second barrier being opposite each other on the second mounting structure, the first and second protrusions positioned complementary to the gaps of the first mounting structure and configured to engage with the gaps, engagement of the protrusions into the gaps providing passive rotational alignment of the first and second asymmetrical surfaces about the optical axis,
• wherein the first and second walls each extend along the optical axis in a first direction, the first and second barriers each extend along the optical axis in a second direction opposite the first direction, wherein an outer surface of the first wall is configured to contact an inner surface of the first barrier and the first protrusion extends from the inner surface of the first barrier toward the optical axis to engage with the gap of the first wall, wherein the inner surface of the first barrier faces the optical axis and the outer surface of the first wall faces away from the optical axis.
