High Reflectivity Mirrors For Laser Applications

Edmund Optics' panel of laser optics experts discuss why the industry standard of measuring transmission to infer the reflectivity of high reflectivity laser mirrors doesn’t tell the whole story.

Protect yourself from throughput loss and laser induced damage!

Join us for a 45 minute webinar presented by Edmund Optics' panel of laser optics experts to learn why the industry standard of measuring transmission to infer the reflectivity of high reflectivity laser mirrors doesn’t tell the whole story. Reflectivity may seem simple, but it is actually a difficult value to measure.

At the conclusion of this webinar, participants will have a strong understanding around:

  • The importance of high reflectivity mirrors for laser applications
  • Why the industry standard method of measuring transmittance and inferring reflectivity doesn’t tell the whole story
  • How to truly verify the performance of high reflectivity mirrors and predict real world performance
