PHOTOTHERAPY OF SKIN WOUNDS

摘要

A method and apparatus for irradiating wounds with UV radiation from which the UVB component is substantially removed or attenuated. UV light from a mercury vapour lamp (1) is passed through a filter (2) and thence through a lens (3) which focuses the radiation onto a target region (18). The filter (2) is formed from a number of alternating layers of dielectric material of different refractive indexes.
