Denmark's Risø National Laboratory and OPDI Technologies have jointly developed a groundbreaking optical chip for computer mouse

Denmark's Risø National Laboratory and OPDI Technologies have jointly developed a groundbreaking optical chip for computer mouse. The OPDI chip is the first of its kind where the laser light source is an advanced optic lens system which is assembled with the other components and detectors on one single chip. A traditional optical mouse contains more than 20 components which need to be assembled.

Steen Grüner Hanson, research specialist at Risø's department for optics and plasma research says: "Our system gives a very accurate determination of speed and direction, and the chip is small, cheap and robust. No one else has been able to develop a miniature optical chip, and the concept opens windows of opportunity in many industrial applications, such as mobile telephones or MP3 players which need a mouse function".

The OPDI chips will be produced by Pixart Imaging Inc in Taiwan, while the technologically advanced lens will be made in Denmark. Deliveries of the chips are expected to start in spring 2006. Risø forecasts annual sales will amount to several million units, generating considerable licence earnings. The news was reported by financial daily newspaper Børsen and on Risø's website.
