Abstract
The present invention is a hand held dermoscopy epiluminescense device with a magnification lens and an associated ring of luminous diodes powered by an on board battery. Every other diode in the ring operates as first and second light sources. The even diodes are filtered by a first polarization ring and the odd diodes are filtered by a second polarization ring. Each polarization ring has an open center for the lens and openings sized and positioned to correspond to the even or odd diodes to only filter one set. A viewing polarizer is provided and is cross-polarized relative to the first polarization ring and is parallel-polarized with the second polarization ring. A three way switch which provides on demand cross-polarized, parallel-polarized and a combination thereof for epiluminescence. A second embodiment provides even diodes of a first color and odd diodes of a second color. A third embodiment employs the alternating colored diodes of the second embodiment as well as the cross and parallel polarization of the light from the diodes as found in the first embodiment.
