Paper Abstract

Multilayer quarterwave stacks were fabricated to reflect at λ = 16 μm. Due to the substantial metric thickness of the stack, the mechanical stress caused the coating to separate from the substrate. The optical thickness of the lead fluoride was 35% thicker than the zinc selenide in the stress-compensated design. The tensive stress of the former compensated the compressive stress of the latter.
