New light pipe material features 60% contrast ratio improvement

8 October 2003 Opto-Electronics

BivarOpto offers a new, optional, high-contrast material for its Light Pipe products family. The second-generation materials provide a 60% improved contrast ratio for light transmission of surface or through-hole mounted LEDs. Featuring the use of a new 94V-O compliant custom polycarbonate compound from GE, the light pipes are white-diffused in off-state appearance and take full colour when in the on-state.

The materials will be available by special order across the Bivar line of SLP, LP, VLPR and PLP Series Light Pipes, and the lens caps of its flexible light pipe (FLP Series) products. These precision moulded products are designed to offer designers a choice of alternative mounting, display and fixturing solutions that carry light from SMD and through-hole LEDs typically mounted on PCBs to front panels of a host of applications. The new higher contrast ratio ability opens the door to uses for indoor displays, office equipment, building automation, motion sensors and motion control applications.
