Description

GENERAL INFORMATION
Tantalum(V) Oxide Patinal® forms hard and environmentally stable films on glass and plastic substrates with low absorption over a broad spectral range from the UV to the SWIR. It shows considerably less absorption than TiO2 and an adjustable stress level depending on coating conditions. It is therefore especially suitable for laser coatings with an extensively high number of layers.

AREAS OF APPLICATION

High quality AR and other optical multilayer coatings for UV, VIS and NIR on glass, crystalline substrates and polymers
Coatings for laser applications with strong requirements on laser damage threshold
High precision filters with low absorption levels
Protective and reflection enhancing coatings on metals in combination with e.g., SiO₂
