SUMMARY
The discussion focuses on solving the reference index problem in nonreflective film coatings applied between lens surfaces. The author proposes a method involving sandwiching the coating and calculating its thickness as lambda/2 multiplied by the reference index. The conditions for destructive interference are examined at both the front and back surfaces of the lens, highlighting the importance of phase differences in reflection. The analysis emphasizes the need for precise equations to describe these conditions due to the complexity of multiple rays emerging from the lens.
