Light pipe homogenizing rods utilize total internal reflection to homogenize non-uniform light sources regardless of their spectral characteristics. TECHSPEC® Tapered Light Pipe Homogenizing Rods are available in both 2X and 3X magnifications. The Numerical Aperture (NA) of the light output is reduced proportionally to the magnification, allowing significant reduction in NA of the output light.
