Simple freestanding 90 deg. filter is used for obtaining the metallic vacuum coatings. As the source of metallic plasma adapted standard cathode vaporizer on the installation ''Bulat 6''. Plasma flow from the cathode flowed through the not protected by isolation spiral (solenoid). The solenoid outlet from the side of cathode find under the floating potential. The second solenoid outlet was connected to the autonomous power supply. Solenoid was prepared with the wide interval of the coil winding and with the turning to 90 degrees. Therefore, drifting charged of particle can freely depart from the interior of solenoid outside. The glow of the turned flow of plasma is observed during the supplying to the cathode and the solenoid. Flow is separation from the coils and is extended along the axis of solenoid. In this case over the solenoid flow the current 20-90 A, the voltage of solenoid relative to vessel (earth) + 15 V. We assume, that this device ensures radial electric field relative to the basic nucleus of the plasma (diameter of the nucleus of plasma column it is commensurate with the diameter of cathode) and the current of solenoid creates the longitudinal magnetic field (estimated order 20 oersted). Magnetic field strength is sufficient for the magnetization of electrons, but it is very small for the ions and the charged microdroplets. The carried out experiments on the application of coatings on the dielectric substrate with the use of aluminum and titanium cathodes showed the effectiveness of the work of this separator. Coatings without the drops are obtained also on the glass substrate with HF- displacement. The reflective properties of the metallic films (Ti,Al) on the glass samples were measured.
