    • An ophthalmic illuminator is disclosed, one embodiment comprising: an illumination source, wherein the illumination source produces an arc; a lens, such as a condensing lens, for focusing light produced by the illumination source arc; and an optical fiber for carrying the focused light to a surgical site, such as an eye. The illumination source is positioned offset from a longitudinal axis of the optical fiber to compensate for shifting of the illumination source arc over time. The offset position can be such that the illumination source is positioned in a vertically offset position from the longitudinal axis of the optical fiber. The longitudinal axis corresponds to the optical path axis of the optical fiber. The ophthalmic illuminator can further comprise a reflector for reflecting the light produced by the illumination source arc, wherein the reflector is positioned offset from the illumination source to decrease the rate of erosion of an illumination source cathode.
    • 公开了一种眼科照明器,一个实施例包括:照明源,其中照明源产生电弧; 用于聚焦由照明源电弧产生的光的诸如聚光透镜的透镜; 以及用于将聚焦光携带到诸如眼睛的手术部位的光纤。 照明源定位成偏离光纤的纵向轴线,以补偿照明源电弧随时间的移动。 偏移位置可以使得照明源位于离光纤的纵向轴线的垂直偏移位置。 纵轴对应于光纤的光路轴。 眼用照明器还可以包括用于反射由照明源弧产生的光的反射器,其中反射器定位成偏离照明源,以降低照明源阴极的侵蚀速率。
