Film-forming materials based on metal fluorides (fluoride FFM) are mainly used such as low-refracting components of the multifilmed interference coatings. The transparency range of these compounds is extended from VUV to IR 10-14 microns.
Depending on the type of the evaporating installation and the chemical composition, FFM can be supplied in the form of granules, tablets and targets of the required size.
For manufacturing optical interference antireflection; anti-reflective; protective coatings on optical parts (prisms, lenses, filters) made of glass, monocrystals, optical ceramics, etc.:
by the method of vacuum electronic-beam and resistive evaporation;
by the method of magnetron and ion-plasma vaporization.
Today our company is the only Russian manufacturer and developer of high-purity materials for thin-filmed optics. We can produce the FFM with the form and size by a customer’s request. Besides we can develop and produce the required FFM composition according to your technical specification.
