This talk will introduce HARMAN technology Ltd (formerly the silver halide manufacturing division of ILFORD Ltd) to the holographic community and launch its range of holographic products. In detail it will give an historical overview of our involvement in holography, recent results, the current applications of our technology, details of the science behind the product, and look ahead at the future for Holography at HARMAN. Ilford began manufacturing holographic products in the 1970’s with major development work in the mid 1980’s launching a range of plates, film and chemistry. This was discontinued in 1991 due to lack of demand. Recent enquires asking if we would consider producing material again has started up our involvement and now work with several clients on a number of different applications. The science and technology behind the large-scale production of silver halide based holographic material has changed since its inception at ILFORD in the 1970’s. I will show images of the recent silver halide crystals grown by HARMAN and explain some of the difficulties around obtaining an accurate determination of their size. Looking forward, HARMAN are working with Professor Richardson from DeMontfort University England and Havels Sylvania lighting to produce edge lit lighting devices for use in buildings to increase the efficiency of flat screen lights and hence enable a significant reduction in energy use. HARMAN is also ready to launch its own range of plates and samples of images made on the plates will be on show at the conference.
