Figure 1 Light intensity of SmartLite PS compared to other curing lights
The SmartLite PS does not - unlike the widely used Quartz-Tungsten-Halogen (QTH) lamp -
emit light with wavelengths beyond the absorbance range of camphorchinone (CQ). CQ is
the most commonly used photo initiator in almost all visible light cured dental materials. Thus
the light emitted by the SmartLite PS corresponds to the absorbance maximum of CQ, which
ensures a very efficient activation and curing of the restorative material (Figure 2).
