The Andover Advantage in Metrology

Advanced measurement solutions for complex optical challenges

Optical metrology is the science of measuring and characterizing optical components and systems. At Andover Corporation, our comprehensive metrology capabilities help verify everything from surface quality and flatness to spectral performance and environmental stability.

How Andover Helps:

  • Performance Validation: We verify optical specifications across UV, visible, and infrared wavelengths using state-of-the-art spectrophotometers
  • Quality Assurance: Our custom-designed interferometer measures transmitted wavefront quality down to 1/20th wave accuracy
  • Environmental Testing: We can simulate real-world conditions with temperature testing from -192°C to +500°C and variable humidity
  • Process Control: Our 100% inspection policy and complete documentation ensure consistent quality throughout manufacturing
  • Custom Solutions: We develop specialized test procedures for unique requirements and challenging specifications

Whether you need standard optical testing or custom measurement solutions, our experienced team can help verify your components meet exact performance requirements. Our metrology expertise ensures quality and consistency from prototyping through production.
