Thin film filters: optical testing with the CTP10 test platform

Challenges and solutions for fast and accurate swept IL-RL measurements

Application note

Thin Film Filters (TFF) are amongst the most versatile and widely used optical components and yet come with unique challenges when it comes to optical testing:

  • free-space optical components
  • IL and RL testing
  • small size, <2 mm
  • broadband testing, usually spanning from the O to the L band
  • final QA testing and in-situ optical monitoring

This application note reviews the challenges and solutions for successful TFF optical testing.
