Abstract

An illumination system providing monochromatic light output includes at least one illumination source providing white light and a monochromatic filter, disposed between the at least one illumination source and an object to be illuminated, for converting the white light to monochromatic light of a predetermined color and/or wavelength.

Claims

1. An illumination system providing monochromatic light output, said illumination system comprising:

at least one illumination source, said a least one illumination source providing white light; and

a monochromatic filter, disposed between said at least one illumination source and an object to be illuminated, for converting said white light to monochromatic light of a predetermined color and/or wavelength.

2. The illumination system of claim 1, wherein said at least one illumination source is a white LED array.

3. The illumination system of claim 1, wherein said at least one illumination source is selected from the group of lighting consisting of a ring light, a DOAL, an SCDI, a CDI.

4. Illumination system of claim 1, wherein said illumination sources mounted in a housing and wherein said housing includes a light diffuser or clear window disposed between said at least one illumination source and said object to be illuminated, and wherein said monochromatic filter is disposed between said illumination source and said light diffuser or clear window.
