The invention relates to a concentricity detection device, which is used for detecting axis concentricity between a lens cone and a microscope stand in a lens mould train. The concentricity detection device includes a light source, a detection rule and a device for detecting an optic axis shift excursion which is opposite to the light resource and is used for recording a projection position of a lens axis and sensing an axis projection shift excursion. The detection rule includes an outer sleeve and an inner sleeve which is arranged inside the outer sleeve; the inner sleeve can be turned at a predetermined angle relative to the outer sleeve and is used for acting in concert with the lens. Furthermore, the invention relates to a concentricity detection method by using the concentricity detection device.

The invention discloses an electric rotating locating device used for a camera polarized lens. The electric rotating locating device used for the camera polarized lens comprises a polarized lens, a polarized lens gear, a driving mechanism, a control mechanism of the polarized lens gear, a supporting mechanism of the polarized lens gear and a substrate. The driving mechanism, the control mechanism of the polarized lens gear, and the supporting mechanism of the polarized lens gear are arranged on the substrate. The polarized lens gear is a hollow ring gear. The polarized lens is embedded in the polarized lens gear which is driven by the driving mechanism to rotate. The supporting mechanism of the polarized lens is meshed with the polarized lens gear and used for supporting the polarized lens gear in a suspension mode. The control mechanism of the polarized lens gear is capable of detecting and sensing a rotating location and a rotating angle of the polarized lens gear, issuing pulse command to the driving mechanism, and controlling movement of the driving mechanism. Therefore, the polarized lens gear is driven to rotate to a set rotation angle. The electric rotating locating device used for the camera polarized lens is capable of controlling rotation remotely and locating accurately the polarized lens.
