Molding Glass Aspherical Lens

  • We can correspond from φ1.0mm minimum size lens to big diameter, exceeds φ30mm
  • Accuracy is Ra0.003um (special quality), we can mold lens in very high accuracy.
  • We can correspond from dozens of trial to tens of thousands of mass production. And, we accept inquiries from optical designs.
