The Visioscan® VC 20plus is a unique UVA-light video camera with high resolution to study the skin surface directly. The SELS® parameters (Surface Evaluation of the Living Skin) have been developed especially for this camera and are used in numerous studies. The images show the structure of the skin and the level of dryness very impressively. The camera can be used on pigmented spots and lesions and on hair. With its multi-functional software, the Visioscan® VC 20plus is a very flexible system to characterize skin surface condition easily, accurately and very economically. It had been used on board of the International Space Station ISS for several years.
The latest Visioscan® generation with improved hard- and software offer a multitude of possibilities:
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.
The applications of this flexible tool are without limitation.
