Design and manufacturing of ophthalmic antireflection coatings with low angular color shift

The residual reflectance colors of broadband antireflection coatings for ophthalmic optics have been investigated as a function of statistical production errors, lateral thickness changes and incidence angle of light. The goal was to design coatings with good production stability, low lateral color variation even over steeply curved lens surfaces and low angular color shift. The investigations show that the final design can only be a compromise between the different requirements.
