An apparatus for applying light in selective frequency ranges to organic composite materials used in restorative dentistry for optimum curing of the composite materials includes a lamp (14) energized by power supply (12) to transmit light through a flexible light transmitting cord (22). A dichroic filter lens (18) is disposed within an end cap (32) detachably securable to the end of a contra angle probe (27) mounted on a hand held handle (28) secured to the end of cord (22) opposite lamp (14). Lens (18) is selected with reference to the particular composite material to be cured so that substantially all frequencies of light produced by lamp (14) are blocked or attenuated except the frequency range which produces uniform and complete curing of the composite material without causing radical cross-linking of the composite material. The desired light frequency range is ascertained by sequentially directing different frequencies of light at a sample of the composite material and measuring the intensity of the light absorbed by the compound at each test frequency. The frequencies of light which are highly absorbed by the organic material without causing radical cross-linking of the material are chosen for the curing process.
