1998

  • Applied Photonics Ltd established in August 1998 by Dr Andrew I Whitehouse, a former employee of British Nuclear Fuels plc who led a small team involved with the development of laser-based materials analysis techniques within the Research & Technology Department at Sellafield. The principal motivation behind the setting up of the new company was to offer a specialist service to industry in the field of laser spectroscopic remote analysis of materials, in particular Laser-Induced Breakdown Spectroscopy (LIBS). Business opportunities were believed to exist in the nuclear, steel manufacturing and glass manufacturing industries with an emphasis on remote chemical analysis of hazardous or high-temperature materials. Other markets were believed to exist in areas such as recycling of metals, alloys and plastics where the rapid, non-contact chemical analysis capabilities of LIBS are seen as offering a unique and cost-effective solution to the practical problems of high-speed sorting of scrap materials.
  • Company employed five staff and set up premises at the Innovation Centre, Westlakes Science & Technology Park, Whitehaven, West Cumbria.
  • Won a major contract with British Energy Ltd to design, manufacture and deploy a fibre-optic LIBS instrument for use at Hinkley Point B and Hunterston B AGR nuclear power stations (see Application Note 001 ).
