Abstract
An integrated image sensor and lens assembly comprises a lens barrel, an adapter tube, and a lens mount. The lens mount includes a first thread having a first pitch and the tube adapter comprises a second thread reciprocal to the first thread. The first and second threads secure the tube adapter within the lens mount. The tube adapter further comprises a third thread having a second pitch different than the first pitch, and the lens barrel comprises a fourth thread reciprocal to the third thread. The third and fourth threads secure the lens barrel within the tube adapter. A rotation of the tube adapter with respect to the lens barrel and the lens mount causes linear movement of the lens barrel and the lens mount with respect to the tube adapter in a same direction along the optical axis.
