Psoria-Light™ Model PS1000 delivers targeted ultraviolet (UV) light to small regions of affected skin (2.88 cm), sparring healthy skin. The system is capable of delivering either UVB light (300 to 320nm) or UVA light (350 to 395nm). Psoria-Light™ Model PS1000 generates both UVA and UVB light via LED technology, avoiding environmental concerns associated with disposal and exchange of mercury gas lamps, Xenon, and Chlorine gases commonly associated with targeted UV phototherapy devices. Psoria-Light's™ UVB LEDs emit light between 300 and 320 nm, avoiding light emissions below 300nm. Psoria-Light™ Model PS1000 incorporates a unique safety feature, a non-contact sensor located about the aperture of the handpiece that detects human skin. The trigger mechanism for UV dosage administration (located on the handpiece) is disabled until a suitable surface is detected by this sensor.
