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.

Description

Background technique [0001] The devices, systems and methods disclosed herein generally relate to the detection of the coupling efficiency of a light beam directed into an optical fiber. [0002] Intraocular illumination probes are 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. Typically, an intraocular illumination probe is connected to an optical port of the intraocular illumination system to receive light from the intraocular illumination system. An intraocular illumination system may include a light source that produces light and a light collector that couples the light into an optical fiber of an intraocular illumination probe. [0003] During assembly of the intraocular illumination system, the position and inclination of the beam from the concentrator are adjusted until the coupling efficiency of the beam into the intraocular illu...
