Abstract
A UV phototherapy apparatus has a base unit containing a UVB arc lamp and an output port for delivery of UVB radiation within a predetermined range. A flexible, elongate optical guide is connected to the output port at one end and to a handpiece at the opposite end. The handpiece is arranged to convert the round beam from the optical guide into a predetermined straight-edged shape such as a rectangular beam, and has an exit aperture of corresponding shape for delivering the shaped beam to a target area of a patient. A beam isolating assembly in the optical path isolates UVB radiation in the predetermined range from the lamp output, so that at least 90% of the radiation directed into the optical guide is in the predetermined range.
