Flexible Light Pipe System with Zero Light Bleed™ Technology

Bivar's the first to offer a flexible light pipe system with innovative Zero Light Bleed adapter technology and optional built-in surface mount LED: an all-in-one solution.

The new flexible light pipe system expands the family and provides even more agility in design to move light long distances, move around obstacles, and easily handle re-designs. The Zero Light Bleed adapter channels light directly to the lens. This 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 Zero Light Bleed  SZ Series is available in a wide variety of options: optional built-in LED, unique fiber colors, and a range of sizes.
