future optical sensor developments.

The consideration is €2,250,000 payable in cash on completion plus an additional

photonics business, we have used Mikropack's light source technology in a wide
range of spectroscopy measurement applications and end-markets for many years. 
The acquisition not only secures this important technology but strengthens our
position in Europe and provides a better platform for further geographical
expansion of all of the Group's photonics products.  Mikropack will join the
Ocean Optics group of businesses to enable these goals to be achieved.'
