Abstract

An ophthalmic laser illuminator 10 includes multiple laser devices 12 - 16 . There are at least three different wavelengths of light emitted by the multiple laser devices 12 - 16 and each wavelength of light emitted by each laser device is outside of wavelengths blocked by a safety filter used for surgical treatment lasers 52 . A controller 18 controls the multiple laser devices 12 - 16 . A graphical user interface 32 is operably attached to the controller 18 for allowing a user to select a plurality of light parameters for a light beam exiting the illuminator 10.

First claim

multiple laser devices, wherein there are at least three different wavelengths of light emitted by the multiple laser devices and each wavelength of light emitted by each laser device is outside of wavelengths blocked by a safety filter used for surgical treatment lasers;
a controller for controlling the multiple laser devices;
a graphical user interface operably attached to the controller for allowing a user to select a plurality of light parameters for a light beam exiting the illuminator;
wherein the graphical user interface allows a color of the light beam exiting the illuminator to be set via multiple color-entry mechanisms including at least a use of a chromaticity graph, a slider bar for each different wavelength of light emitted by the laser devices, a plurality of color preset buttons, a numeric entry of a color coordinate of the color desired, and a numeric entry of a proportion of each wavelength comprising the light beam exiting the illuminator;
wherein the graphical user interface allows a luminous flux level of the light beam exiting the illuminator to be set via multiple flux-entry mechanisms including at least a master slider bar and a numeric entry of a luminous flux value; and
wherein, after the graphical user interface is used to set the color and luminous flux level of the light beam exiting the illuminator via one of the multiple color-entry mechanisms and one of the multiple flux-entry mechanisms, the graphical user interface automatically updates all of the multiple color-entry mechanisms and the multiple flux-entry mechanisms to reflect the set color and luminous flux level.
