Alignment Units for the MultiCentric® Cementing

The MultiCentric® Cementing Workstation aligns and cements lens pairs quickly and accurately with an accuracy of better 2 µm. During the alignment process the upper lens is either aligned to the optical axis of the lower lens or to a mechanical axis, e.g. the axis of an arbor. To provide cementing solutions for all lens geometries and manufacturing processes TRIOPTICS offers different alignment units which can be placed on the OptiCentric® Cementing or MultiCentric® Cementing Workstation.

Alignment Unit Standard
Alignment Unit Standard

Alignment Unit Standard

The Alignment Unit Standard aligns and cements lenses with a sample geometry of D/(2R) ≤ 0.7¹. The unit can be easily adapted to different lens sizes and is therefore more flexible when different doublets need to be aligned within short notice.

 

 

Technical Data of the Alignment Unit Standard

  Coaxial alignment (3 surfaces)
Sample geometry ¹ D/(2R) ≤ 0.7
Alignment accuracy Better 2 µm
Lens diameters ² 4 - 90 mm
Time for change-over to other sample type (predefined set up) 10 s
Cycle time with MultiCentric® measurement head 10 s

¹ D = lens diameter, R = radius of curvature of the intermediate lens surface of the doublet
² other diameters on request

Alignment Unit Advanced

The Alignment Unit Advanced was developed to overcome the limitations of the Alignment Unit Standard. All kinds of lenses can be aligned with this unit, including:

  • hemispherical lenses
  • lenses with D/(2R) > 0.7
  • doublets where the edge of the upper lens in not accessible
  • lenses with tight tolerances for cement wedge
