Abstract
The invention relates to a light wave converter assembly, comprising a light guide and a light wave converter, comprising a converter substance, which converts a part of the incident light into light of a longer wavelength, whereby the converted light is guided together with the unconverted light through the light guide to an exit port.
Claims27
A dental illumination or transillumination system, comprising a photopolymerization system and a light wave converter assembly with a light guide and a light wave converter,
- wherein the light wave converter exhibits a converter substance operable to convert a part of incident light into light of a longer wavelength, whereby the converted light is guided together with a portion of the unconverted light to an exit port;
- and the light, converted by the converter substance, together with the unconverted light yields a light with the wavelength spectrum of the color white in order to illuminate hard tooth substances.
Process, comprising the steps:
- a) provision of a light wave converter assembly, comprising a light guide and a light wave converter, wherein the light wave converter exhibits a converter substance, which in use converts a part of incident light into light of a longer wavelength, and wherein the converted light is guided together with a portion of the unconverted light to an exit port, and b) connection of the light wave converter to a polymerization device, c) at least one of illumination and transillumination of hard tooth substance with light which is generated by the polymerization device and is converted by the light wave converter.
