Systems and methods of microbial sterilization using polychromatic light

Abstract

The present invention is a device for sterilizing microorganisms on a liquid or solid substrate. The device includes a light source for producing a light and an optical device positioned proximate the light source. The optical device is configured to focus the light generated by the light source to provide a high intensity light output. The optical device also includes a dichroic reflector. The dichroic reflector is configured to pass thermal energy generated by the light source and reflect the light produced by the light source. The device also includes a power supply, where the power supply is coupled to the light source and the optical device. The device thereby killing microbial organisms presented within the range of the high intensity light output.

What is claimed is: 
     
         1 . A method for delivering a high energy UV light to a substrate comprising:
 a. selecting a high energy light that delivers a high energy UV light without thermal energy; and   b. delivering the high energy light without thermal energy to the substrate.
