Indentation University Session 8: How to Test Optical Coatings

In Session 8 of the KLA Instruments Indentation University series, we discuss the measurement of flexibility and strength of optical coatings, and why these parameters are important for coating performance.

About this Webinar

Session 8 covers the importance of the mechanical strength and flexibility of optical coatings, using dynamic nanoindentation on an anti-reflective coating (AR coating or ARC) as an example. This webinar includes a demonstration of the coating measurement, including sample preparation and loading into the iMicro nanoindenter. The experimental setup for optical coating nanoindentation testing is covered, including the recipe settings and starting values, and a demonstration of the nanoindentation testing process is performed and narrated, with interpretation of the testing results. The concept of indentation strain rate is also introduced.

Note: for Session 8, it is recommended to view the following Indentation University webinar as background for the discussion:
