Abstract
The present disclosure provides a casing and a lens and relates to the technical field of optical equipment. The casing includes an outer casing provided with an accommodating hole and an inner casing accommodated in the outer casing and provided with a mounting hole. The outer casing is made of metal material, and a hardness of the inner casing is lower than a hardness of the outer casing, thereby the outer casing can meet the metal shape requirements of the lens. The relatively soft inner casing can solve the problem that a metal material cannot be tightly fitted with the lens group. The casing not only has advantages of metal profiles, but also can take a fitting structure with stacked outer diameters and a bumpy ridge fitting structure into account due to providing the relatively soft inner casing inside, which is more beneficial for lenses with high performance requirements.
