Description

GENERAL INFORMATION
Substances H4 and H4 HD Patinal® are high refractive index evaporation materials for the vacuum deposition of highly transparent homogeneous thin film coatings. They are composed of a mixture of titanium oxide and lanthanum oxide to form a stable LaTiO₃ phase. Substances H4 and H4 HD Patinal® allow for very stable process conditions as well as stress compensation in multilayer stacks and are thus very well suited for high precision optical coatings.

AREAS OF APPLICATION

High quality AR and other optical multilayer coatings for NUV, VIS and NIR on glass, crystalline substrates and polymers
High precision filters requiring low stress levels
Low absorption coatings on temperature sensitive substrates such as polymers
Protective and reflection enhancing coatings on metals in combination with e.g., SiO₂
