Another is Nokia, which is world famous for cellular phones and telecommunications, and the other is Polar Electro which is known for heart-rate monitors. In general, the history of optics in Finland is in instrumentation and scientific measurements. People talk about video phones and so on. About 10 years ago, I was in Finland, and the primary focus of optics and optoelectronics in Finland seemed to be related to some of the major industries in the area, such as forestry and paper manufacturing and things of that kind. Forest industries and machinery industries are important users of optical instrumentation and sensors.
Technical solutions are now much more advanced.
As an example I would mention the recently developed tools for industrial imaging spectrometry. However, new optics applications have evolved, too. Optoelectronics is now increasingly used in consumer products and in everyday life. For example, the optoelectronic control of water taps in bathrooms is rapidly expanding as Harri already mentioned. A major challenge will be wireless communication with multimedia properties.
