Abstract:
A method and apparatus are disclosed for a LED used in a medical device emitting a wavelength from about 200 nanometers to about 440 nanometers along a path. A composition of phosphors coats the LED to broaden the electromagnetic spectrum from about 200 nanometers to about 780 nanometers. A filter is positioned in the path to selectively permit electromagnetic radiation of a particular range of wavelengths to pass through. The medical device is used to provide a broad spectral source for medical diagnosis.
