The present invention provides a hand held dermoscopy epiluminescense device
having a generally circular optical magnification lens incorporated into the housing
of the device. A lighting array provides the light necessary for medical examination
of the skin. The lighting array comprises a ring of LEDs comprising four different
colored sets of LEDs each on a different lighting circuit. The four colors comprise
White, UV/Blue (405 nm), green/yellow (565 nm) and orange/red (630 nm). A second
embodiment provides 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. The device is threaded to mate with a camera or camera lens.
