Alignment measuring instrument OptiCentric® Bonding 5D

opticaloptical lensprocess

The OptiCentric® Bonding 5D Station has been developed to achieve the highest accuracy requirements when precision optics are aligned and bonded within a cell. The system automatically aligns a lens within a cell so that the optical axis of the lens coincides to the axis of symmetry of the cell in tilt and shift. During this process the lens is not supported by the cell, but is hold on a ring chuck which can be aligned to any axis within the cell. Furthermore, the Bonding Station determines the axial gap in the Z direction between a reference surface, e.g. the upper flange surface of the cell, and the lens vertex using the integrated OptiSurf® low-coherence interferometer. It then shifts the lens to the target position Key Features Alignment of lenses in a cell in 5 degrees of freedom Positioning accuracy of the system: x/y/z <1 µm θx,θy < 2arcsec (Alignment accuracy of the lens depending on the sample) Short cycle time < 5 min (without glue dispensing and UV curing) Fully automated alignment process Stable process, independent from the qualification of the operator Quick and easy change-over to other sample type
