    Abstract: An optical fiber detector, and a method and system for optical fiber detection are disclosed. One embodiment of the optical fiber detector of this invention comprises: a receptacle, to receive and position an optical fiber connector; an infra-red ("IR") source for providing an incident IR beam onto a cross-sectional face of an optical fiber and a cross-sectional face of the optical fiber connector; and an IR detector for receiving a reflected IR beam from the face of the optical fiber and the face of the optical fiber connector and generating a detector signal representative of the intensity of the reflected IR beam, wherein the intensity of the reflected IR beam is representative of the presence and type of the optical fiber. This embodiment of the optical fiber can further comprise an IR filter for filtering non-IR wavelengths from the reflected IR beam before the IR beam is received at the IR detector and signal processing and control means, for receiving and processing the detector signal to provide display, control or monitoring functions. The receptacle can be part of an illuminator system enclosure housing a light source, wherein the receptacle is further operable to position the connector such that the optical fiber is optically coupled to the light source. The infra-red source can comprise an IR light emitting diode ("LED") and the IR detector can comprise a photodiode operable to detect IR wavelengths. The intensity of the reflected IR beam can vary, and is inversely proportional to the ratio of the area of cross-sectional face of the optical fiber reflecting the incident IR beam to the area of cross-sectional optical fiber connector reflecting the incident IR beam. Embodiments of this invention can be implemented within any fiber-optic illuminator machine or system for use in ophthalmic or other surgery. Further, it is contemplated that the optical fiber detector of this invention can be implemented or incorporated in any machine or system requiring connection of an optical fiber to a light source. Other uses for an optical fiber detection method and system designed in accordance with the teachings of this invention will be apparent to those familiar with the art.

    Abstract: A filter and method for filtering an optical beam are disclosed. One embodiment of the filter is an optical filter for filtering an incident light beam, comprising an optically effective material characterized by: a light transmittance of less than 1% for wavelengths below 420 nm; and a light transmittance for wavelengths complimentary to wavelengths below 420 nm that, combined with the transmittance for wavelengths below 420 nm, will yield a filtered light beam having a luminosity of about 90% and an excitation purity of 5% or less. The complimentary wavelengths can be wavelengths above about 640 nm, wavelengths above about 660 nm, and/or wavelengths from about 540 nm to about 560 nm. Further, in one embodiment the difference between the light transmittance just below 420 nm and the light transmittance just above 420 nm can be greater than 90%. Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined. The optically effective material can be optical-grade glass, an optical-grade plastic or polymer, a thin-film dielectric coating, or an optical-grade glass or plastic coated with a dielectric coating. The optical filter can be mounted downstream of an illumination source exit aperture, wherein the illumination source produces the incident light beam, and upstream of a site to be illuminated by the filtered light beam. Alternatively, the optical filter can be operably mounted on a set of viewing optics of a surgical microscope to filter a reflected portion of a light beam produced by an illumination source and used to illuminate a site, such as a surgical site.
