Which outcome reduces fringe contrast on coated optics?

💡 Explanation

Increased substrate thickness variation causes varied optical path lengths, therefore reducing constructive and destructive interference of reflected light, which is the mechanism causing fringe patterns, rather than other options maintaining interference.
