title: Development of narrow-band lamps for testing and clinical use.
abstract: A compact narrow band lamp for high intensity irradiation has been developed. It consists of a high-pressure mercury lamp, a shutter and water cooled filters for spectral isolation of the light. A mixing device permits simultaneous irradiation with two different wavelenghts by using two lamps. The spectral distribution of the light within the bands is given for seven filter combinations. The construction and calibration of a power meter is also described.
