In contrary to conventional colour skin cameras, the Visioscan® VC 20 plus features a unique UV-A LED illumination (proven to present no hazard to normal human skin) in a small, easy-to-handle, ergonomically designed plastic casing. The light is homogenously distributed by a reflector. In addition, the camera consists of a high-resolution b/w video sensor chip, an objective and the new “liquid lens technology”, an electronically controlled lens which automatically adapts to the skin surface distance and maximizes the range of depth of field.
The results are impressive, non-glossy images of the skin surface (size approx. 10 x 8 mm) displayed in 255 grey levels. Wrinkles and lines appear dark and skin scaliness can be seen as very bright pixels. The software analyses the image regarding a variety of topography parameters.
