How Does a Vein Finder Work?

What are Vein Finders? Vein Finders are optical devices that use the behavior of Infrared light to create an image and superimpose project it onto the viewing area. Infrared light is projected onto the viewing area and is absorbed at the locations where blood (veins) reside. Where light is absorbed there is less light reflected. This is accomplished with separate rows if infrared LED lights one row at a time. When this is done very quickly in a scanning fashion a digital image is created and superimpose projected onto the viewing area. The AV300 is an excellent device that produces bright, clear images.
