Oscillating Tool Technology (OTT)

Proven in specialty contact lens, IOL, and ICL production for more than 20 years, the DAC OTT is the Z’-axis fast tool solution for manufacturers producing non-rotationally symmetric lens geometries. The OTT provides synchronized motion with the spindle — enabling the precise, repeatable Z’-axis excursion that non-rotationally symmetric surfaces require, without the complexity of separate fast servo hardware. 

Whether you’re producing toric lenses, prism-ballasted designs, slab-off geometries, or weighted lenses, the OTT handles the full range of concave and convex non-rotationally symmetric configurations. Up to 2 mm of tool excursion covers the displacement ranges needed for stabilization and orientation features in both specialty contact lens, IOL, and ICL designs. A high-speed air turbine drill marker is included for axis referencing and diagnostic marking. 

  • 20+ years of proven deployment in specialty contact lens, IOL, and ICL production environments 
  • Z’-axis fast tool with synchronized spindle motion — concave and convex non-rotationally symmetric geometries 
  • Up to 2 mm tool excursion for the full range of prism, slab-off, and weighting feature depths 
  • Supports designs with and without prism, slab-off, and weighting features 
  • Included air turbine drill marker for axis referencing and marking 
  • Compatible with ALMe, ALM, and MLC platforms
