An optical module, comprising:
- a lens group comprising at least a first lens consisting of a cut-edge lens;
- a lens barrel with an inner cavity, wherein the first lens is movably provided within the inner cavity;
- a guide slot, is provided on a side wall of the lens barrel along an axial direction;
- a transmission member, through which a periphery of the first lens is slidably matched with the guide slot via a transmission member;
- a focusing ring, slidably provided on an outer side of the lens barrel;
- and
- an inclined slot, provided on a wall of the focusing ring close to the lens barrel, and the transmission member passes through the guide slot and is slidably connected to the inclined slot;
- wherein the focusing ring is configured to be slid in a circumferential direction of the lens barrel, and the inclined slot is configured to drive the transmission member to slide within the guide slot, so that the first lens moves translationally along the axial direction of the lens barrel to match a visual acuity of a target object for focusing.
