The present invention provides an apparatus for white light observation and fluorescence diagnosis of skin diseases. More particularly, the present invention provides an apparatus for photodynamic diagnosis in which a plurality of excitation light emitting diodes (LEDs) is provided in an image pick-up head, the excitation LEDs being arranged to illuminate the entire examination region in the form of a mosaic by setting respective illumination light axes of the excitation LEDs to illuminate preassigned individual areas of the examination region, thus uniformly illuminating the examination region in a wide field of view with excitation light. In the apparatus for photodynamic diagnosis, the respective excitation LEDs are provided at the same or different angles based on the light axis of the object lens, and thereby it is possible that the beams of the light sources composed of the LEDs illuminate the field of view of the examination region uniformly, thus improving the uniformity of illumination. Moreover, the present invention provides an apparatus for photodynamic diagnosis in which warm white LEDs and cold white LEDs as white light sources are appropriately arranged so as to deliver natural colors and thereby to reproduce natural color images.

The present invention provides a laser apparatus for medical treatment using pulse trains, in which the skin is cooled to a given temperature and then one or more laser pulses are applied to a to-be-treated region at specific intervals, thereby alleviating a pain associated with a skin disease and activating a dermis layer. According to the present invention, a pain caused during the treatment process is alleviated by using laser pulse trains and a cooling unit, and heat energy is transferred to only a dermis layer of a to-be-treated region without eliminating an epidermis layer of the to-be-treated region, thereby remarkably improving the treatment recovery period and the frequency of treatments as compared to the conventional treatment method.
