Light pipes and homogenizing rods
Light pipes and homogenizing rods are used in light source system, UV light, LED light guide, projection lamp , and projection lens, the incident lights of homogenizing rod with numerous internal reflections can homogenize the lights.
Control Optics specializes in manufacturing homogenizing rods in cylindrical, cone, quadrilateral, hexagonal, octagonal, and aspheric shapes. For projection lens products with strict quality requirements, we are able to provide chamfer free, chipping free high-precision homogenizing rods, available for AR coating on incident surface or emergent surface. Please contact us for your requirements.
