Disclosed is a front barrel eccentricity measurement jig that enables simple and quick measurement of lens eccentricity of the front barrel of a camcoder. The device can measure the eccentricity of the lens secured on the object stage. The object stage(16) comprises a pair of symmetrical support column(11), a bearing(12), a connector(13), a knurl(15) along the lower circumference of the object stage(16). The front barrel eccentricity measuring mechanism comprises an eccentricity measurement jig(10), an object lens(41), an eyepiece(42), a body tube(44), a frame, and support(43). The camcoder body tube is composed of a rear barrel and a front barrel(20). The top of the connector(13) is pressed fit to the inside diameter of the bearing(12). The jig enables measurement of eccentricity from various directions with a single setting of the lens.
