Abstract: An illumination apparatus has a first adaptor, an illumination apparatus body, and a light emitter housing. The first adaptor can be removably attached to a viewing device. The illumination apparatus body is removably coupled to the first adaptor and defines a viewing aperture. The light emitter housing is coupled to the illumination apparatus body and disposed laterally from the viewing aperture. A movable block is disposed in the light emitter housing so as to be movable with respect to the light emitter housing. A light emitter is disposed within the movable block such that the movable block is capable of being moved so that light emitted from the light emitter can be directed toward the viewing center axis of the viewing aperture.

Abstract: A lighting apparatus includes a thermally decoupled lighting component holder. The component holder includes a component holder body defining a fiber optic receptacle and a light source receptacle. The fiber optic receptacle is disposed in the lighting apparatus housing, and has an internal surface configured to retain at least a portion of a fiber optic cable. The light source receptacle is disposed in the lighting apparatus housing apart from the fiber optic receptacle by a predetermined distance so that the fiber optic receptacle is at least partially thermally decoupled from the light source receptacle. Such a light source receptacle has an internal surface configured to retain at least a portion of a light source that is disposed within the light source receptacle. The fiber optic receptacle and light source receptacle are arranged so that light emitted from said light source is directed into the light receiving end of the fiber optic cable.

Abstract: A lighting device can include a housing having a viewing axis and at least one light source. The light source can be comprised of at least one LED, and can be configured to emit light having a spectrum that approximates a noon-day sunlight spectrum. The light source can be disposed in or coupled with the housing, and oriented with respect to the housing so that the emitted light has an angle of incidence from about 15 degrees to about 75 degrees. Thus, the emitted light can have an angle from about 15 degrees to about 75 degrees with respect to the viewing axis. The lighting device can be used to compare the color of different materials having different compositions. Also, the lighting device can be used to illuminate objects that are sensitive to IR and/or UV light.
