GENERAL INFORMATION Thin films made from yttrium fluoride can be used for optical coatings from the UV to the MIR spectral range and show very good durability. They pass environmental tests of moderate abrasion, tape and adhesion even after 24 hours of humidity. AREAS OF APPLICATION
Multilayer coatings for UV, NIR and MIR spectral range
Alternative to thorium fluoride for coatings in the IR spectral range
