The Dialight 515-1004F Optopipe™ is a rectangular light pipe designed for use in applications requiring optical signal transmission through a plastic housing. It is ultrasonically welded to the customer’s plastic housing using a tab at the top. The light pipe material is water clear transmissive polycarbonate rated UL94-V0, and has a 35% oxygen index. Suitable LED light sources, such as Dialight's 597 Series PLCC-2 or PLCC-4 Type SMT LEDs, are recommended. Dialight offers custom Optopipe solutions for specific applications.
