Abstract

The present invention relates to a device for treating of superficial afflictions of the type telangiectasis by means of a directed light beam. The device can be produced at a very low cost compared with known devices due to the fact that a source of light (2) that produces non-coherent light is used, that means due to a non-use of laser.

Claims

1. A device for the treatment of undesired superficial skin afflictions such as telangiectasis, comprising:

light transforming means for transforming a first predetermined wavelength band of light to a second predetermined pulsed wavelength band of light;

a first light source for producing light including said first predetermined wavelength band; and

guide means for directing said second predetermined pulsed wavelength band to a predetermined location.

2. The device of claim 1 wherein said first and second wavelength bands have a width of up to 10% of the peak wavelength in said band.

3. The device of claim 1 wherein said first and second wavelength bands have a width of up to 5% of the peak wavelength in said band.

4. The device of claim 1 wherein said light transforming means is a light transforming liquid solution.

5. The device of claim 4 wherein said solution comprises a dye solution.

6. The device of claim 1 wherein said light is pulsed from about 0.1 to about 10 milliseconds.

7. The device of claim 1 wherein said light is pulsed from about 0.1 to about 2 milliseconds.

8. The device of claim 6 wherein said light has a pulse frequency ranging from about 1 to about 1,000 hertz.
