Bivar's Low-Profile Flexible Light Pipe System with ZeroLightBleed™ Technology

The SZR Series flexible light pipe system expands the SZ Series with a right angle flexible light pipe system that is low-profile for applications that need LED light routed in a tight space. This product is ideal in enclosures where the height is limited, and space is constrained.

The ZeroLightBleed™ adapter is designed to capture as much light as possible at the LED source. It also eliminates disruptive light bleed in and around the circuit board, which is known to cause false readings, muted and blended colors, and unwanted glow in the chassis.

The individual system components have been paired to best optimize the system. Color is used on the fiber jacket for visual identification when more than one SZR light pipe system is used in the same application. With the right angle adapter, we have solutions for vertical and horizontal board placements.


The ZeroLightBleed™ SZR Series is available in a wide variety of options: lens styles, unique fiber colors, and IP54 protection.

Available in 1mm and 2mm Optical Fiber Diameter
Standard lengths 1” – 3,940” or customize to fit your specific application requirements
Optical Fiber jacket comes in the following color options: Black, Red, Green, Blue, White, Yellow

Features & Benefits

Simplified sourcing

Bivar uses a modular approach which makes sourcing a flexible light pipe simple by offering a right angle flexible light pipe system that is low-profile for applications that need LED light routed in a tight space.


Optimum compatibility

Designed with the most compatible LED, flexible light pipe, and lens combination, the ZeroLightBleed™ flexible light pipe system provides maximum light transmission while eliminating light cross talk between light pipes. The SZR Series is designed to capture as much light as possible at the entrance and when more than one SZR light pipe system is used in the same application, color is used on the fiber jacket for visual identification.

Applications & Insights

Many customers with applications in Industrial Automation, Robotics, Data Center, Agriculture, and Telecom Infrastructure use indication to communicate more than simply on or off.

RGB SMThe ZeroLightBleed™ adapter technology allows you to use multiple colors in close proximity without color crosstalk. Individual parts have been paired to best optimize the system when using our LED surface mount chip parts like SM0402, SM0603, SM0805 or SM0807. This is a good entry level product for prototyping and development.
