Laser illumination system
View Patent ↗An ophthalmic endoillumination system comprises a self-contained power source and a laser light source powered by the self-contained power source to produce light. The system further comprises an elongated member sized for insertion into an eye and for conducting the light produced by the laser light source.
1. An ophthalmic endoillumination system comprising:
a handpiece;
a self-contained power source housed within the handpiece;
a laser light source housed within the handpiece and powered by the self-contained power source to produce light, the laser light source comprising a plurality of lasers;
an elongated member coupled to the handpiece and sized for insertion into an eye and for conducting the light produced by the laser light source; and
at least one optical component positioned to receive and redirect a light beam from one of the plurality of lasers, wherein the at least one optical component includes a diffraction grating.
2. The ophthalmic endoillumination system of claim 1 wherein the elongated member includes a cannula.
3. The ophthalmic endoillumination system of claim 1 wherein the elongated member includes an optical fiber.
4. The ophthalmic endoillumination system of claim 1 wherein the produced light is monochromatic light.
5. The ophthalmic endoillumination system of claim 4 wherein the monochromatic light is green light.
6. The ophthalmic endoillumination system of claim 1 wherein the produced light is polychromatic light.
7. The ophthalmic endoillumination system of claim 1 wherein the plurality of lasers include a first laser for generating monochromatic blue light, a second laser for generating monochromatic red light, and a third laser for generating monochromatic green light.
8. The ophthalmic endoillumination system of claim 1 further comprising a lens arranged to receive the produced light and transmit condensed light to the elongated member.
9. The ophthalmic endoillumination system of claim 1 further comprising a lens arranged to receive the light conducted by the elongated member and to alter the angular spread of the light.
10. The ophthalmic endoillumination system of claim 1 wherein the self-contained power source includes a battery.
11. The ophthalmic endoillumination system of claim 1 further comprising a connector for removably connecting the elongated member to the handpiece.
