1. A method comprising:
identifying, by a processor of camera modular alignment and test (CMAT) equipment, a set of camera components and a corresponding set of lenses that are loaded into the CMAT equipment for producing a portion of a final camera assembly;
controlling, by the processor, the CMAT equipment to:
dry-fit assemble the lenses with the camera components; and
execute an initial five-axis lens alignment check that measures an initial modulation transfer function (MTF) performance for the lenses when dry-fit assembled with the camera components;
determining, by the processor, whether the initial MTF performance satisfies a MTF threshold; and
responsive to determining that the initial MTF performance satisfies the MTF threshold, further controlling the CMAT equipment to:
apply an ultraviolet curable adhesive material to interfaces on surfaces of the camera components;
dry-fit assemble the lenses with the camera components after the ultraviolet curable adhesive material is applied;
execute a subsequent five-axis lens alignment check that measures subsequent MTF performance for the lenses when dry-fit assembled with the camera components after the ultraviolet curable adhesive material is applied; and
cure the ultraviolet curable adhesive material with ultraviolet radiation for outputting the portion of the final camera assembly if the subsequent MTF performance satisfies the MTF threshold.
