1st European electro-optics markets and technology conference and exhibition
1st European Electro-Optics Markets and Technology Conference and Exhibition
Geneva
1 2 - 1 5 September 1972
The Geneva Conference and Exhibition come at a time when more interest is being shown in electro-optics than ever before. A sudden spate of discoveries and developments over the last two years has been followed by a quite exceptional degree of commercial interest and the commercial interest has in its turn encouraged a further burst of technical activity. To mention one field - fibre-optic communications -- important technical barriers have been broken many times during the last few months. One national communications authority stated recently that if attenuation in fibre-optic waveguides could be lowered to 20 dB krn-~, then fibre-optic communications would become extremely competitive. Since then, three groups in the UK, Australia and the USA have produced fibres with attenuations well inside this limit. We will be hearing more on this in the session on electro-optic crystals. Important developments have also been taking place in the field of holography. Possibly the first credit for developing holographic techniques which are likely to reach the shop floor must go to the Loughborough University team who developed the speckle pattern interferometer. Very recently, however, important advances have been made in hologram interferometry - especially improved techniques of in situ plate processing. An example of this will be showing on one of the stands in the exhibition. A measure of the commercial progress in electro-optics is to be found in the many new products that are being displayed for the first time in Geneva - only a few months after another electro-optics exhibition in Brighton. On practically every stand there will be at least one entirely new product. Notable examples are the first commercially available modelocked dye laser and a very simple, inexpensive interferometer that could become a standard piece of equipment in a wide range of industries. The conference programme and exhibition at Geneva have been designed with two groups of people in mind. The first includes engineers and scientists representing small research firms, government research establishments and universities. These will be on the look out for fresh ideas. The second group embraces the ever-growing numbers of marketing men and their opposite numbers in the buying departments of large manufacturing companies. Judging by the information which has been flowing into our offices immediately before the exhibition, both types of visitor will be more than pleased that they came.

for HIGH TEMPERATURE APPLICATIONS Operational up to 150°C, EMR's Multiplier Phototubes are used world-wide in geophysical and thermal-nuclear investigations. Within these environments, EMR'S tubes demonstrate a capability beyond any other phototube requiring high shock, vibration and temperature characteristics. All EMR tubes are individually calibrated, tested, and delivered with complete test data sheets for every major performance parameter.
PHOTODIODE STANDARDS for PHOTOMETRIC CALIBRATION EMR offers a line of photodiodes as secondary standards for ultraviolet radiant intensity calibration. These photodiodes are calibrated from 116.4 nm through 253.7 nm at eleven wavelengths. The calibration is traceable to the National Bureau of Standards, providing a reliable laboratory standard for photometric calibration. For further information on EMR products, call~write
