  • Interference filter and method for producing it
    Patent number: 8000002
    Abstract: The invention is based on the object of providing UV interference filters having improved long-term stability. For this purpose, a method for producing a dielectric transmission interference filter is provided, in which an alternating layer system having the constituents magnesium fluoride, lead fluoride and antimony oxide is produced on a substrate by co-evaporation. After deposition, the substrate is subjected to heat treatment and irradiated with UV light in order to stabilize the layer system.
    Type: Grant
