  • Optical lens, camera module and corresponding assembly method
    Patent number: 11849203
    Abstract: A method for assembling an optical lens includes preparing a first lenses part including a first lens and a second lenses part including a second lens, capturing the first lenses part, and adjusting a posture of the first lenses part according to a distance measurement result, so that an included angle between a first end surface of the first lenses part and a second end surface of the second lenses part is less than a threshold of inclination angle. The method also includes adjusting the first lenses part at degree of freedom of linear movement to complete pre-positioning, performing an active alignment of a position of the first lenses part at the degree of freedom of linear movement according to an actual imaging result, and fixing the first and second lenses parts together, so that their relative positions are maintained at the relative positions determined by the active alignment.
