A GOOD EXAMPLE OF UNCONVENTIONAL THIN FILM PROCESS DEVELOPMENT AND ENGINEERING

A really good example of thin films process development resulting on NOT fighting environmental effects in application of the product. Most of the time we design and develop thin films to resist the environment (denser films, boundary layers, etc.). This process engineer allows for environmental shifting post process before measuring the final result.

The process engineer was having trouble with an ophthalmic AR coating shifting out of colour specifications after the coating was allowed to absorb atmosphere for 24 hours. The engineer designed the coating to shift into spec. An option we too often overlook.
