Intelligent LED curing light. Its Polyvision technology helps clinician ensure a more effective polymerization of light-cured dental materials: it alerts the clinician if he/she moves the curing light probe away from the tooth while curing and dynamically adjusts the curing time to compensate for the movement. Polyvision is like a vehicles lane departure warning system because it helps the clinician keep the curing light probe focused on the tooth for more effective polymerization of the dental material. Device also features Polywave technology, which provides a broad wavelength spectrum of 385515nm, which allows the light to cure all dental materials on the market today. 3-year warranty.
