4 Summary

This document described the following:

  • Details on the optic selection for 3D ToF cameras
  • Difference in the lens requirements for 3D ToF cameras and typical cameras
  • Basic concerns while designing or choosing lens mounts for a given lens

Very few lenses available in the free market fit the requirements of 3D ToF cameras. It is useful to identify sources of compatible lenses and share it with the community. Usually these sources would be geared to supply small quantities. Sharing the lens source with the community would help drive prices down by increasing volumes.
