Coating on Chalcogenide Materials:
Chalcogenide materials have a known reputation of having adhesion issues after thin film deposition layers are applied. Through innovative deposition techniques, Reynard has developed a durable thin film coating process on materials such as Amorphous AMTIR (-1, -2, -3, -4, and -5), Schott IG (-3, -4, and -6), and Lightpath BD-2. Many variants of anti-reflection and filter coatings have been validated on these materials for spectral and durability compliance directly by customer third-party testing. Coatings can be applied to plano (flat), concave, and convex surfaces. In-house testing includes Mil-Spec thermal cycling, humidity testing, adhesion, and abrasion. Additional custom testing programs can be defined and implemented, as well.
