GENERAL INFORMATION Substance M3 Patinal® (aluminium lanthanum oxide) is a medium refractive index material for evaporation, covering a wide transmission range from UV to IR. Its refractive index fills a gap not available from non-mixture materials. Since layer stress can be influenced through the adjustment of coating conditions, Substance M3 Patinal® provides additional freedom for the design of high-performance optical multilayers on a variety of substrate materials.
AREAS OF APPLICATION
AR coatings for UV, VIS and NIR
Multilayer coatings for filters, mirrors, beam splitters etc.
