The VeinViewer by Luminetx™ utilizes near infrared light and patented technologies to illuminate subcutaneous vasculature by imaging their location on the surface of the skin. VeinViewer is a mobile biomedical device consisting of the following four components:

1. Infrared light source - The light source emits a harmless, near-infrared light reflected back to the surface from the tissue surrounding the vein, while no light is reflected back from the blood inside the vessel.
   
2. Digital video camera - The digital video camera captures the near-infrared light reflected back from the patient.
   
3. Image processing unit - The microprocessor adds contrast and projects this image back on the skin in their actual location.
   
4. Digital image projector - Using Texas Instruments Digital Light Processing™ technology, the projector displays these real-time images of the vasculature onto the surface of the skin.
