Lens quality control:

To ensure the quality of our lens before expedition a 100% inspection is made by SINOPTIX own QC. Control may include:

  •  Aspect (scratch & dig)
  • Dimensions
  • Radius of curvature
  • Surface quality (interferometer)
  • Transmission
  • Focal length measurement
  • Sag (profilometer)
