Abstract

Mercury and halogen lamps that possess mutually supplementary spectral responses are used simultaneously in an illuminator intended for phototherapy and fluorescence diagnosis. Their radiation is summed and delivered to an object through a liquid lightguide. Two summation methods--spectral and angular--are tested experimentally. The best results are given by the latter method, in which convergent beams from the lamps are directed into the lightguide at different angles. The total optical power at the lightguide output is 14.5W in the 300-800-nm range. The working spectral interval is selected by means of switchable interference filters on command from a built-in processor. The influence of the spectral width of the radiation on the efficiency with which the radiant flux is used is estimated.
