LIGHT ENGINE FOR IMAGING SYSTEM

A light engine for a nano-arthroscope assembly includes a light source, wherein the light source includes a light emitting diode (LED) mounted to a circuit board; a collimating optic positioned proximate to the LED, wherein the collimating optic collimates light emitted from the LED and increases an intensity of the light emitted from the LED; a ball lens positioned to receive the light collimated by the collimating optic, wherein the ball lens focuses the received light to a focal point outside of the ball lens; and a bundle of light fibers positioned proximate to the ball lens, wherein the bundle of light fibers includes a first end that is positioned at the focal point of the light focused by the ball lens such that the light is coupled into the first end of the bundle of light fibers at the focal point.
