Compound lens assembling method, compound lens assembled by the same, and camera

A compound lens assembling method of assembling a plurality of single lenses of a compound lens such that optical axes of the single lenses are aligned with each other, said compound lens assembling method comprising the steps of:

• pressing the single lenses disposed respectively on the opposite sides of a cylindrical spacer against the spacer by a pair of chucking units having center axes aligned with each other and capable of moving in directions parallel to the optical axes of the single lenses;
• and
• fixing the single lenses to the spacer by a fixing means with the curved surfaces of the single lenses on the opposite sides of the spacer in contact with contact surfaces of the chucking units and the spacer contained in planes perpendicular to the optical axis, respectively, and with the single lenses and the spacer automatically centered.
