Bichromatic white ophthalmic illuminator
First Claim
1. An ophthalmic endoilluminator comprising:
- a light source having only a first monochromatic light source emitting a first light and a second monochromatic light source emitting a second light, the first and second lights defining a light color axis representable on a chromaticity graph;
a collimation element configured to collimate at least one of the first and second lights;
a mixing device configured to mix the first and second lights into a single light beam;
a lens configured to focus the single light beam;
an optical fiber configured to carry the single light beam; and
a controller coupled to at least one of the first and second monochromatic light sources, the controller configured to;
determine from the chromaticity graph a combination of the first light and the second light that corresponds to a point along the light color axis on the chromaticity graph that represents a specific color; and
tune at least one of the first and second monochromatic light sources according to the determined combination to yield the single beam of light at the specific color.

Abstract
An ophthalmic endoilluminator having only a first monochromatic light source emitting a first light and a second monochromatic light source emitting a second light. The first and second lights defining a light color axis representable on a chromaticity graph. A collimation element configured to collimate at least one of the first and second lights. An optical mixing device configured to mix the first and second lights into a single light beam. A lens configured to focus the single light beam. An optical fiber configured to carry the single light beam. A controller coupled to at least one of the first and second monochromatic light sources. The controller configured to tune at least one of the first and second monochromatic light sources such that the single beam of light represents a specific color of light at a point along the light color axis on the chromaticity graph.

16. A method of providing illumination to an interior of an eye, the method comprising:
-
providing a light source having a first monochromatic light source and a second monochromatic light source; providing current to the first and second monochromatic light sources to cause the first and second monochromatic light sources to emit a first and second light, respectively; determining from a chromaticity graph a combination of the first and second lights that corresponds to a point on a light color axis of the chromaticity graph that represents a specific color; controlling the first and second monochromatic light sources such that a single beam of light produced from the first and second lights is the specific color; collimating the first and second lights; mixing the collimated light to yield the single light beam; focusing the single light beam; and transmitting the single light beam over an optical fiber. - View Dependent Claims (17, 18, 19, 20)
