Thông tin sản phẩm

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



Applications

Aligned lens in cell
Aligned lens in cell
  • Assembly of lenses with highest requirements for accuracy

 

 

Process of Directional Adhesive Bonding

 

 

Process of Directional Adhesive Bonding

  1. The adhesive is applied to the edge of the lens and the spatial positions of the lens axis and cell axis are measured;
  2. The lens is aligned in the cell in four degrees of freedom;
  3. The axial gap between the apex point of the lens and a reference surface is measured and the lens adjusted axially;
  4. The adhesive is cured;
