Precision Optical Polishing & Fabrication

Advanced optical solutions from raw material to finished component

What is Custom Polishing and Fabrication? Andover Corporation transforms raw optical materials into precision-engineered components through our advanced polishing and fabrication processes. Using a combination of automated CNC equipment and expert craftsmanship, we create custom optical solutions that meet exact specifications across diverse applications - from prototype development to high-volume production. Our in-house capabilities allow us to control every aspect of the manufacturing process, ensuring consistent quality while maintaining faster turnaround times than traditional outsourcing methods.

Our capabilities include:

  • Polishing a wide variety of materials to very precise specifications
  • Achieving transmitted wavefront errors down to 1/10 wave
  • Parallelism to within a few seconds of arc
  • Sizes ranging from a few millimeters to 250mm and larger
  • Automated processes for consistency and repeatability

Whether you need a filter that's 2mm or 350mm, Andover has fully automated CNC equipment to fabricate exactly what you need, with the quality you expect, and using the optical material of your choice.
