An optical screening device for detecting abnormal skin tissue indicative of disease including a handle having an elongated stem adapted for holding the optical screening device in one hand and a head for housing an array of light emitting diodes with each diode in the array being spaced apart to form a given geometry with each diode selected to emit light in a wavelength range between 340 nm to 470 nm; a high pass filter supported by said handle in close proximity to said array of light emitting diodes with the filter being of a size to provide a defined viewable area for visibly detecting irradiated light reflected from skin tissue under observation and adapted to block light at least below 400 nm; and a source of electrical power for energizing said array of light emitting diodes. |
