«FotEst-LED» laboratory LED photo-polymerizer intended for photo-polymerization of facing light-sensitive dental materials. Light source on the basis of diodes emitting in blue spectrum (peak wave length 475 nm) is the photo-activator of polymerization process. Application: «FotEst-LED» is intended for application at dental laboratories and could be used: -at facing technique with any dental alloy; -at preparation of jacket crowns including frames on gypsum model; -at prosthetic restorations; -at fabrication of cores and veneers used in therapeutic dental practice. Peculiarities of the device design: -Two types of emitter: 12 semiconducting LED (basic source) and 1 halogen lamp (additional light source that allows to carry out polymerization process with orthopaedic unit heating); -Electronic timer; -Light and sound indication; -Automatic blocking of polymerization mode at working chamber opening; -Built-in fan for emitter cooling.
