The Flexible Light Pipe FLP5 series offers a wider viewing area, enhanced contrast, and reduced light loss. According to the company, these devices provide brighter transmissions of LED-based lighting to display and indicator panels up to several hundred feet away. The devices suit industrial control, automotive, medical, datacom/telecom, and mobile electronics applications. The FLP5's enhanced brightness is achieved with a round 7-mm (nominal) lens size. This series features a viewing area that is 4 mm larger than previous versions. The FLP5 is designed with a clear honeycomb lens structure. Maximizing LED light emission, it reduces light loss from the typical 4% to under 3%. This design also increases the number of light-dispersing Fresnel details from two to four.
The company's patent-pending bonding technology creates a monolithic structure of lens and plastic optical fiber (POF). Flame-retardant UL-rated flexible tubing can extend to reach virtually any LED location on the pc board up to 328 ft. away. The FLP5 series devices are available in through-hole and surface-mount configurations. Custom sizes and colors are also available. Typical FLP5 pricing in production quantities is about $0.75 for a full assembly in 6-ft. length.

The MAXIMISER is a versatile 1/2 VGA display unit. According to the company, this unit achieves increased performance at a price comparable to existing QVGA displays. The MAXIMISER incorporates a 6-in. diagonal screen. This passive monochrome display is available in two versions: negative mode (STN) and positive mode (FSTN). Both versions provide a viewing area measuring 125.5 mm wide and 87.2 mm high. While the dot pitch is 0.25 by 0.25, the dot size is 0.23 by 0.23. The unit incorporates a low-power CFL backlight (less than 2 W over 10,000 hours of life). The operating-temperature range of the unit is −15°C to 70°C. It also features a storage-temperature range of −20°C to 70°C. While the STN version offers extreme brightness (over 100 cd/m2), the FSTN version is sunlight-readable. The STN version is transmissive. Since the FSTN version is transreflective, it can be used with or without a backlight. Both models can be used in grey-scale mode.
In 1000-unit quantities, pricing for the displays starts at $70.
