棱镜的接触角的测量

Sessile drop contact angles were measured with water on two types of plastic lens with a standard FTÅ200 instrument. One lens had an antireflection coating and the other did not. The purpose of the measurement was to both show the differences between the lens coatings and the process of making measurements on the "side" of a lens where the surface is obviously not flat. A secondary purpose was to see if the curvature of the lens was sufficient that local baseline correction was necessary.
