1. An adjustable optical lens of a camera module comprising an optical sensor, comprising:
an optical structural member having an internal space along an axial direction thereof; and
two or more lenses, wherein said lenses are spacedly preassembled in said internal space of said optical structural member along an axial direction of said optical structural member, wherein one or more positions of at least one of said two or more lenses in said internal space of said optical structural member is able to be adjusted in horizontal direction, vertical direction, tilt direction, and peripheral direction for calibration and measured to generate a MTF (Modulation Transfer Function) value by capturing an image through said lens and the optical sensor;
wherein said optical structural member has at least one adjustment channel adapted to communicate said internal space of said optical structural member with an external environment, and said lens is arranged in said internal space of the optical structural member corresponding to said adjustment channel, so that at least one position of said lens in said internal space of said optical structural member is able to be adjusted through said adjustment channel by controlling a needle inserted into said adjustment channel; and
wherein said lenses are preassembled in said internal space of said optical structural member with an adhesive, wherein the adhesive is in a half solidified condition, wherein said adhesive is a mixed adhesive of an UV adhesive and a thermosetting adhesive, and is in the half solidified condition after ultraviolet exposure to achieve the preassembling, and wherein after a heating process, said adhesive becomes completely solidified, so as to affix said lenses.
