Inspection/Measurement for the “Inclination” and Slant of the Centering” of the Both sides ( Top surface and Bottom surface) of lens Decentration at the same time.
DFD-1000 and SDF-100 are two systems highly powerful and user friendly tool for lens centration and decentration process in lens manufacturing. Readings captured, via video CCD system, by DFD-1000 or SDF-100 are sent to a software, running on a PC, for data processing. Target focusing module is used to find the best focus view.
DFD-1000 is designed with a top and bottom objective to scan the lens' surface and uses motorized up-down focus mechanism. SDF-100 is designed with single top objective to scan the lens' top surface and manual up-down focus mechanism.
The accuracy of the system is ? 2 micron and is extremely useful and user friendly in process such as mobile phone camera lens and photography camera lens manufacturing.

Kunoh comes from Japan, engaged in the research and design for examining the optic and accuracy measuring equipment, and developed the products that conform to customers’ demand in X axis measurement. Besides the 3D measuring microscope, for matching the development of photo-electric industry, it brought the dual type precise lens centering measurement apparatus in 2004, the dual-side measuring function is leading in the field, and has been the important basis of speed measurement and good ratio improvement for lens manufacturers.
