Application Phototherapy

Phototherapy is the oldest form of treatment for many skin diseases and is based on the positive effect of sunlight. In particular, the radiation components in the ultraviolet (UV) range have proven to be very effective in the treatment of numerous skin diseases. Lamps that generate artificial UV light have been used in medicine since 1899 and can be used to treat skin diseases in a targeted manner. Since then, there have been many successful efforts in research and technology to further improve this form of therapy and minimize side effects. Today, therefore, light sources with specially selected spectra are available and modern therapy devices enable precise dosage of the UV light.

Special light meters are also available to control the intensity of the UV light, with which the skin is irradiated in order to avoid damage during therapy.

Test system for MED/MPD* systems in phototherapy

MED/MPD* systems are used in medical phototherapy to determine the optimum UV dose for every individual patient. They must be calibrated on a regular basis

MPP (Mini Pen Probes) detectors are specifically de- signed for the wavelength ranges of these systems. In combination with the innovative functions of the handh- held light meter ILT2400, they enable comfortable monitoring of MED/MPD testing devices.

MPP are available in three configurations:
