Abstract: PROBLEM TO BE SOLVED: To provide a system and method for effectively and efficiently reducing or removing light of undesired wavelength from a light source. SOLUTION: The present invention provides the system and method for filtering light. Concretely, the system is prepared as a source of illumination using one or more mirrors in an optical path and can filter light. In one embodiment, one or more cold mirrors on the optical path are coated so as to reflect light of desired wavelengths while transmitting light of the other wavelengths. As light from a light source is selectively reflected by the cold mirrors, the light of undesired wavelengths can be substantially removed before the light from the light source illuminates an area. In other embodiments, one or more hot mirrors are provided on the optical path, wherein the hot mirrors are coated so as to transmit the light of desired wavelengths and reflect the light of undesired wavelengths.

Abstract: A high-efficiency, wide-angle illumination surgical system is disclosed, one embodiment comprising: a light source for providing a light beam; an optical cable, optically coupled to the light source for receiving and transmitting the light beam; a handpiece, operably coupled to the optical cable; an optical fiber, operably coupled to the handpiece, wherein the optical fiber is optically coupled to the optical cable to receive and transmit the light beam; an optical element, optically coupled to a distal end of the optical fiber, for receiving the light beam and scattering the light beam to illuminate an area, wherein the optical element comprises a compound parabolic concentrator (“CPC”) cone; and a cannula, operably coupled to the handpiece, for housing and directing the optical fiber and the optical element. The optical element can be a small-gauge, diffusive optical element comprising a sculpted distal end of the optical fiber or a machined or injection-molded plastic CPC-cone. For example, the optical element can be a 19, 20 or 25 gauge optical element. The CPC-cone optical element angularly spreads the light beam out to a high off-axis angle and emits the light out of the distal end of the cannula with high efficiency.

Abstract: A transparent illuminated infusion and incision cannula is provided for illuminating an area during eye surgery. An endo-illuminator (103,204) comprises a hose (104) operable to transport a fluid, a protective sheath (210) operable to combine the endo-illuminator and hose within a single cable, an incision cannula (602) operable to incise the sclera of the eye, and a transparent cannula (108) surrounding the incision cannula, wherein the transparent cannula is positioned coaxially with the endo-illuminator and a space is defined between a distal end of the endo-illuminator and proximal end of the transparent cannula. The incision cannula (602) is spring-biased between a retracted position and an extended position, such that in its initial position, the incision cannula is extended to enable an incision in the sclera to be made, and is adapted to be retractable to a second position so as to leave the endo-illuminator (103,204) and transparent cannula (108) in their correct relative positions, such that the space between the distal end of the endo-illuminator and proximal end of the transparent cannula allows fluid to flow around the distal end of the endo-illuminator, into the transparent cannula, and into a sclera aperture.

Abstract: Embodiments of the present invention provide a system and method for filteri ng light. More particularly, embodiments of the present invention may filter light provided as a source of illumination by using one or more mirrors in an optical path. In a specific embodiment, one or more cold mirrors in the optical path are coated such tha t they are operable to reflect light in the desired wavelengths while transmitting othe r wavelengths of light. Thus, as light from a light source is reflected off these cold mirrors undesired wavelengths of light may be substantially removed from the light before it i s utilized to illuminate an area. In other embodiments, one or more hot mirrors mirror may also be provided in the optical path, where these hot mirrors are coated such that they are operable to transmit the desired wavelengths of light and reflect undesired wavelengths.
