ABSTRACT:
A slit lamp for illuminating an eye comprises several LEDs electrically coupled to an LED driver. A user input accepts input for a length, a width and an intensity of a shaped beam of light. An LED driver selectively drives a set of LEDs of an LED array to form a shaped light beam having a desired size across a beam cross-section. In some embodiments, several optical fibers at a first end of a fiber optic manifold are optically coupled to LEDs of an LED array, and an optic is placed near a second end of a fiber optic manifold. Several ends of optical fibers of the fiber optic manifold are optically coupled to the set of selectively driven LEDs, and are arranged so as to form the shaped light beam having a desired size across the beam cross-section.
