Developed to achieve the highest accuracy requirements during alignment of a lens in a cell, the OptiCentric Bonding 5D Station has been introduced by Trioptics.
The system automatically aligns a lens within a cell in five degrees of freedom so that the optical axis of the lens coincides with the axis of symmetry of the cell in tilt and shift. The lens is not supported within the cell, but can be shifted to any target position on a lens holder.
In addition, the OptiCentric Bonding 5D 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. The integrated OptiSurf low-coherence interferometer is used for this purpose. After the measurement, the lens is positioned in the Z direction. The system achieves positional accuracies of: 1µm in x,y,z direction; and 2 arcsec in θx,θy direction.
The process-based and user-friendly software means the system can also be operated by less qualified staff. The short process time of five minutes – without applying cement and UV curing – ensures cost-effective production of these high-performance optics.
The system is designed for lens geometries from 10mm to 150mm and cell geometries from 20mm to 260mm diameter, and can quickly and easily be adapted to the respective lens geometry.
