In 1954, Techtron moved to small cottages in Market St. South Melbourne, and in 1957, won a tender to build electronics modules for Atomic Absorption Spectrophotometers (AAS) to CSIRO specifications.
This merger brought great strengths to Techtron in the way of manufacturing techniques, financial support, and perhaps most importantly, a worldwide distribution network for its products.
In 1970, Geoffrey Frew donated a substantial sum to the Australian Academy of Science 'in recognition of the successful commercial development of atomic absorption spectrochemical analysis, which had been originated by Dr A. Walsh of the CSIRO Division of Chemical Physics in 1954'.
The Geoffrey Frew Fellowships enable distinguished scientists from abroad to travel to Australia to participate in the Australian Spectroscopy Conferences and to visit scientific centres around the country.
Cary had long been known as the 'Rolls-Royce' of UV-Visible spectrophotometers and now the total responsibility for the manufacture, marketing and future development of these products lay with the Australian company.
