title = "Optical and environmental performance of nonradioactive infrared optical coatings",
abstract = "A recent program at Pilkington Optronics (Barr \& Stroud) has resulted in the identification of a nonradioactive thorium fluoride replacement film material with reduced toxicity. As described in this paper, the materials has been incorporated into high-efficiency single and dual-band AR coatings for germanium, zinc selenide, and zinc sulphide, without compromising optical and durability performance.
