poLight selects Texas Instruments for optical MEMS expertise

Date Announced: 23 Feb 2012

Solution to scale poLight production capacity to reach camera phones in large volumes.

Horten (Norway), February 23rd, 2012 – poLight, the world leader in reflowable autofocus actuated lenses, announced today that it has collaborated with Texas Instruments to produce in large volume the Optical MEMS part of its TLens™, resulting in faster focus time and lower power consumption.

poLight is developing three different actuated autofocus devices based on a patented technology using Optical MEMS and polymer to fit in camera modules based on 1/5” up to 1/2.5” sensors, reaching 5MP to 12MP and higher resolutions. The device called ‘TLens’ (Tunable Lens) is to replace the traditional VCM (Voice Coil Motor) technology and will enhance camera module performance in terms of speed (more than 20x faster) while consuming 40x less power to preserve battery life in continuous autofocus mode. Those significant improvements will enable new mobile capabilities such as Instant FocusTM or All in FocusTM that are not currently possible due to VCM technology performance limitations.

“Texas Instruments with their MEMS engineering expertise and their worldwide manufacturing operation significantly strengthen our ability to serve our camera module customer demands,” said Christian Dupont, CEO of poLight. “I believe that combining TI technology and manufacturing strength with poLight TLens innovation is optimum to best serve poLight large volume camera module customers worldwide.”

Texas Instruments worked very closely with poLight to develop a process that met the device performance needs while at the same time met cost goals. “The new TLens device from poLight AS benefits from TI’s advanced MEMS development and processing expertise along with TI’s experience in very high volume manufacturing,” said Faa-Ching Wang, manager of the Heater Chip Business Unit at Texas Instruments. “TI and poLight have collaborated on this innovative device that will help bring greater autofocus performance and functionality to camera phone applications.”
