OptiCentric® Cementing Station - Automatic cementing of achromatic lens systems Jun 30, 2011

With OptiCentric® Cementing Station this cementing process can be significantly simplified and automated for more reliable results. In contrast to the traditional process this method eliminates the need for precision sample fixtures, and due to the fully automatic procedure it is independent from the mechanical skills and attention of the operator.
The centration error is measured with an autocollimator system in reflection.With the patented SmartAlign® algorithm the centration of each lens surface within the achromatic doublet is measured automatically and the optimum shift for the upper lens is calculated.This movement is then done within 1-2 seconds with a piezo driven manipulator,achieving a residual centration error between both lenses in the doublet of typically less than 2 microns.
