Abstract
An optical medical diagnostic system is disclosed comprising a LED light assembly, a controller portion and a power portion where the modular LED light assembly can switch from one operating wavelength LED light assembly to another wavelength LED light assembly. The generated fluorescence image may be viewed through a fluorescence band pass filter assembly mounted on the light handle and viewing angle can be adjusted through its tilt arm. The band pass filter blocks the excitation wavelength and passes the fluorescence wavelength.
