                              Gooch & Housego PLC

                            Half-Year Trading Update
                                        

Gooch and Housego PLC, the specialist manufacturer of acousto-optic and
electro-optic devices, precision optical components, crystals, instruments for
measuring optical radiation and hyperspectral imaging systems, today announces a
trading up-date for its half-year to 31 March 2006.


Trading for the first half-year is in line with expectations, being ahead of the
same period last year and reflecting the trend towards a more even distribution
of sales and profits throughout the year. With the exception of ChromoDynamics
Inc., which has yet to commence trading in earnest, each of the group companies
has made a positive contribution to the overall performance.
