ABSTRACT:
The invention relates to an apparatus for an efficient photodynamic therapy treatment. The apparatus comprises the following parts: (a) a lamp possessing a narrow beam light with half angle divergence up to 10.degree., possessing an intensity of at least 2 mW
m with a spectral region in the range of 610 to 750 nm; (b) a glass lens to focus the beams of the light; (c) a red filter possessing a transmittance of 0.95 which provides a spectral region of above 610 nm, and (c) a light guide in the range of 3 to 12 mm diameter, which provides a minimum irradiance of 50 mW/cm.sup.2. According to a preferred embodiment the lamp is provided with a fixed internal reflector. In order to transmit the useful radiation and to remove the heat produced by the infra-red radiation, a 45.degree. dicroic mirror is attached to the apparatus.
