Rigid Light Pipes are available in two mounting types include board mount and press-fit and are available in different configurations and sizes. They are made from optical grade 94V-0 polycarbonate which is designed to be used with the Bivar narrow view LED which channel more light with less bleed. Rigid Light pipes move light in short distances.

Flexible Light Pipe Systems A flexible light pipe system is comprised of two items; an adapter and a 1mm or 2mm diameter optical fiber with lens cap assembly. The adaptor is mounted directly to the PCB and the lens cap is connected to the panel. This two piece press-fit installation allows for convenient hot-swap removal, removes the current in hazardous environments and provides ESD protection for sensitive components. Flexible Light pipes move light greater distances.
