Abstract: An ophthalmic illumination apparatus can include a movable support. The apparatus can also include an optical array coupled to the movable support and positioned to interact with a light beam from a light source. The optical array can include first and second optical elements. The first optical element can be configured to reflect and transmit first associated amounts of the light beam. The second optical element can be configured to reflect and transmit second associated amounts of the light beam different than the first optical element. The apparatus can further include a drive mechanism coupled to the movable support. The drive mechanism can be configured to cause the movable support to selectively move the optical array such that the light beam is selectively incident upon one of the first optical element or the second optical element. Associated devices, systems, and methods are also provided.

Abstract: An ophthalmic endo-illumination system includes a light source producing a light beam, a beam splitter configured to split the light beam into a first beam provided to a fiber port and a second beam coupled to a monitoring fiber, and an alignment system for aligning the monitoring fiber. The alignment system includes a moveable ferrule housing having the monitoring fiber secured therein and a displacement mechanism for displacing housing in a first direction. The displacement mechanism includes a transfer spring coupled to the housing and a screw actuator having a sloped surface contacting a motion transfer ball such that movement of the screw actuator causes the motion transfer ball to move along the sloped surface, the motion transfer ball contacting the transfer spring such that movement of the motion transfer ball along the sloped surface causes a displacement of the transfer spring, thereby displacing the housing in the first direction.

Abstract: An ophthalmic endo-illumination system includes a light source that produces a light beam, a fiber port that receives an optical fiber, a condenser that couples at least a portion of the light beam into the optical fiber received at the fiber port, and a beam splitter disposed between the fiber port and the condenser. The beam splitter is configured to receive the light beam from the condenser and split the light beam into a first beam which is coupled to the optical fiber and a second beam which is coupled to a monitoring fiber. An optical sensor is provided to detect an amount of the second beam output from the monitoring fiber. The coupling efficiency of the first beam coupled into the optical fiber may be determined based on the amount of the second beam output from the monitoring fiber.
