  • Homogeneous UV curing

  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

  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.

  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
