The National Facility is well-equipped to measure surfaces, as  required:-

  • To close the process-loop in polishing, as polishing is inherently an iterative process
  • To support error-compensation in CNC grinding
  • To certify conformance of parts manufactured in-house to specification
  • To certify quality of parts acquired from elsewhere, e.g. null test-lenses

The Facility also uses dimensional metrology to establish the correct distances and angles when aligning optical tests in general, and null-tests in particular.
