Abstract: A device for selectively controlling illumination from a source that emits illumination along an optical path toward an output has an intensity control apparatus for selectively controlling the intensity of illumination at the output; a filter adapted to be selectively disposed in the optical path; and a unitary mechanical user input for controlling the intensity control apparatus and for, when the intensity is at a maximum, permitting selective disposition of the filter in the optical path.

Abstract: An optical connector for connecting an optical cable having a cylindrical endpiece to a light source has a structure having an interior bore with a longitudinal axis, a port for receiving an illuminating beam and another port for receiving the cylindrical endpiece. A channel is defined along the periphery of the bore in the structure. A generally circular shaped spring member is positioned in the channel. The inner diameter of the circular shape is slightly smaller than the outer diameter of the cylindrical endpiece, which allows the establishment of a secure, yet releasable, connection between the cylindrical endpiece and the spring member. If the person wearing the headset connected to the optical cable moves too far, the optical cable is released from the housing.

Abstract: A device for providing radiation to a selected incident location has a first light emitting device adapted to emit light in a band having a peak at a first wavelength, a plurality of second light emitting devices adapted to emit light in a band having a peak at a second wavelength, the second light emitting devices being arranged circumferentially about the first light emitting device, at least a first optical component to receive light from the first light-emitting device and to provide light to the selected incident location; and at least a second optical component to provide light from the second light emitting devices to the selected incident location.

Abstract: A light tip has a bundle of optical fibers extending from a proximal light-transmitting aperture to a distal light-transmitting aperture and an opaque sleeve about the bundle. The proximal light transmitting aperture has a first cross-sectional shape and the distal light transmitting aperture has a second cross-sectional shape. At least some of the optical fibers in the bundle taper from a relatively larger diameter at the proximal aperture to a relatively smaller diameter at the distal aperture. The surface area of the proximal aperture is greater than the surface area of the distal aperture. The cross-sectional shape of the light tip smoothly and continuously changes from the first cross-sectional shape to the second cross-sectional shape through at least a first portion of the light tip. The light tip has a curved section intermediate the proximal and distal apertures.

Abstract: A microscope body has coupled thereto a lens with the axis of said lens relatively transverse to the optical axis of said microscope. A mirror is positioned with respect to said lens to deflect any light propagating through said lens relatively parallel to the optical axis of said microscope and through the objective lens of said scope to the object plane; and a fiber optic cable is directed at one end to propagate light from a remote source through said lens and thence, to said mirror. Means are provided to prevent spurious light or reflections from the surface of the objective lens from appearing at the visual plane of said microscope.
