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.

Description

[0001] related application [0002] This disclosure is related to US Patent Application Serial No. 14 / 468,696, filed August 26, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to ophthalmic illumination, and more specifically to submicron alignment of monitoring optical fibers for optical feedback in intraocular illumination systems. Background technique [0004] Intraocular illumination probes can be used to provide illumination during eye surgery. In particular, intraocular illumination probes may be inserted into the eye to provide illumination inside the eye during ocular surgery. An intraocular illumination probe can be connected to the light port of the intraocular illumination system. The intraocular illumination system may include a light source that generates light and a light collector that couples the light into an optical fiber of the intraocular illumination probe when the endoi...
