Light-polymerization chamber that cures materials for jewelry, dental, and otoplastic applications. Two photo-flash lamps at the bottom of the curing chamber operate in a work mode with a frequency of 10 flashes per second and produce a very intensive light radiation in a spectrum from 300nm to 700nm. Because of this intensive light radiation, materials are hardened better, yielding good physical values and reduced residual monomer content (versus using other lamp types with different light-emitting spectrums).
