“…in 1948 Hilger amalgamated with the well-known metrology instrument manufacturer E R Watts and the company became known as Hilger & Watts…In 1993 the company became reacquainted with an old friend. Jarrell Ash who are part of the Thermo Electron group of companies. Hilger Analytical became part of Thermo Electron in that year….In order to strengthen the Crystal Materials Group of Hilger Analytical it was decided to form Hilger Crystals Ltd. in 1997…In July 2004 Thermo Electron sold Spectra Physics to Newport Corporation who are based in the US. In order to strengthen and reinforce the Hilger brand the product line was re branded back to Hilger Crystals.. a name that is 130 years old!!” Source: http://www.hilger-crystals.co.uk/history.asp ; Adam Hilger, Ltd. ; E.
