Device for measuring lens eccentricity

A lens eccentricity measurement device, comprising:

• a support portion for supporting a lens, the support portion comprising a plurality of gear teeth and a first through hole, wherein the gear teeth are positioned on a circular edge of the support portion, and wherein the first through hole is defined in the support portion;
• an eccentricity detector positioned above the lens for measuring eccentricity of the lens;
• a driving device comprising a driving mechanism and a motor, wherein the motor rotates the driving mechanism and the driving mechanism cooperates with the gear teeth;
• a vacuum absorption device comprising an air pipe and a vacuum generation element, wherein the vacuum generation element removes air from the air pipe;
• a clamping device comprising a first clamping element and a second clamping element, wherein the first clamping element cooperates with the second clamping element to locate and fix the lens;
• and
• a rotatable pole comprising a second through hole, the rotatable pole supporting the support portion.
