Dual-Path Eccentricity Tester（P/N: LensCT-DAF）is a high precision, non-contact optic-centration testing equipment with Dual measurement head. Both measurement head could auto-focus and detect the Lens centering for single Lens and Lens module, with the equipped precision air bearing, and especially good for large aperture lens testing and assembly, and for infrared material as well. The friendly software can directly record the data and show the testing result in required way, and make the actual measurement simply and efficiency

It could also expand the functions to measure the Focal length(including effective focal length, front focal length and back focal length), MTF，Air-Gap and Radius of Curvature, as well and realize one-stop detection of the main optical parameters of lenses and lens module.
