The Radii Plus is a powerful, cordless, lightweight curing light using an LED for the polymerization of composite restorative materials that contain the photo-initiator Camphorquinone. The Radii Plus produces a strong blue light in the wavelength range of 440 – 480 nm, the relevant range for Camphorquinone containing products. The Radii Plus features a ‘NO RAMP’ mode and ‘RAMP’ mode for convenient polymerization shrinkage minimization of composite materials. In addition to this, the LED attachments can be changed depending on the clinical application.
