LIGHT BRUSH 2

Light Brush 2 is an Er:YAG laser system optimized for the cleaning of artworks. Er:YAG laser cleaning is based on the strong absorption of the 2940 nm wavelength from superficial layers containing OH bonds.
Many studies have shown indeed that Er:YAG laser exposure of a surface dampened with a liquid containing – OH groups effectively removes old varnish and other encrustations without inducing unwanted chemical or physical changes on the original surface. For this reason, Light Brush 2 is particularly suitable for the removal of overpaintings and varnishes from wall and easel paintings. Light Brush 2 is an innovative tool for restorers thanks to variable energy emission from 50 mJ to 500 mJ and to adjustable pulse duration.
