Abstract: An ophthalmic illumination system can include an optical fiber configured to transmit a light beam output by a light source and focused by a condenser. The optical fiber can include proximal, distal, and central portions. The proximal portion can be configured to receive the light beam focused by the condenser. The distal portion can be configured to emit the light beam to illuminate a surgical field. The central portion can extend between the proximal and distal portions. A core diameter of the proximal portion can be larger than core diameters of the central and distal portions. An ophthalmic illumination method can include focusing, using a condenser, a light beam emitted by a light source onto a proximal portion of an optical fiber. The method can also include transmitting, using the optical fiber, the light beam to a surgical field.

Abstract: An ophthalmic illumination system includes a light source to emit a light beam and a filter comprising a clear region to transmit visible light in the visible spectrum and a first filtered region to transmit visible light in a first spectral range. The filter is arranged within the optical path of the beam. The system includes a plurality of chromaticity sensors to receive a portion of the light beam transmitted by the filter and output a signal indicating chromaticity of the received beam. The system also includes a processor to receive the signal indicating chromaticity, compare the indicated chromaticity to a target chromaticity stored in memory and, based on the comparison, adjust the chromaticity of the light beam transmitted by the filter by generating a signal to move the filter from a first position in which the light beam is incident upon only the clear region to a second position in which the light beam is partially incident on both the clear region and the first filtered region.

Abstract: A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.

Abstract: Systems, apparatuses, and methods of and for an ophthalmic illumination system are disclosed. In an exemplary implementation, an ophthalmic illumination system includes a collimator having at least one lens. The system includes a first mirror arranged to reflect light towards the collimator. The first mirror is configured for use with a first light source that emits a first light beam having a first parameter. The system includes a second mirror arranged to reflect light towards the collimator. The second mirror is configured for use with a second light source emitting a second light beam having a second parameter that is different than the first parameter. The second mirror is shaped and arranged to cause a reflected portion of the second light beam to have the first parameter. The first mirror and the first light source, and the second mirror and the second light source, are separately usable with the collimator.

Abstract: An optical coupling efficiency detection assembly includes a first housing accommodating a beam splitter and a fiber port, a second housing accommodating a ferrule enclosing a monitoring fiber, and an attachment block attaching the first housing to the second housing to establish a parfocal arrangement among the beam splitter, the fiber port, and the ferrule. Further, an assembly method for the optical coupling efficiency detection assembly is disclosed. The assembly method may include providing a beam splitter and a fiber port in a first housing, providing a ferrule enclosing a monitoring fiber in a second housing, and attaching the second housing to the first housing via an attachment block to establish a parfocal arrangement among the beam splitter, the fiber port, and the ferrule.
