The TechSpec family of light pipe homogenizing rods is for OEM illumination needs. The rods use total internal reflection to turn a non- uniform light source into uniform illumination and deliver it to the target site. These rods are for applications where point sources such as LEDs must be combined and made to deliver even lighting. Unlike traditional square integrating rods, these rods have a hexagonal cross section. The hexagonal shape provides a better match to spherical point source wave fronts, resulting in a 35% increase in coupling efficiency, allowing these light pipes to deliver brighter illumination for a given light source.
