Microscope projection screen by Vickers (1960s)

This is a microscope projection screen made by Vickers (Figure 1), probably dated to the 1960s. According to Vicker’s catalogues of the time, the “… unique 6’’ diameter micro-crystalline wax viewing screen can be fitted to the head … (of a microscope) … providing a swivelling well-illuminated projection surface”. The scientific instrument maker T. Cooke & Sons (1837 – 1922) was founded by Thomas Cooke in York in 1837. Thomas Cooke built his own factory on Bishophill, York, in 1855, producing a great range of spectacles, telescopes and other items. By the turn of the century, defence products for the home market had also become an important field of the company. In 1915 the control of Cooke's was acquired by Vickers Ltd., an engineering firm of shipbuilding and aircraft, who had long had an interest in the military side of Cooke products. Cooke’s continued to expand in York and in 1922 they merged with the long-established instrument-making firm of Troughton & Simms of London (1824-1922). The new firm became Cooke, Troughton & Simms and in 1924 it became a wholly owned subsidiary of Vickers. After the war microscopes, survey equipment and engineers' measuring instruments became the main products. In 1963, following the acquisition of the C. Baker Ltd microscope factory, the new company of Vickers Instruments was formed. This company continued for many years, mainly selling microscopes, surveying instruments and micro measurement apparatus. In 1989 the business was sold to Bio-Rad Micromeasurements, an American company based in California, apart from the defence products, which were acquired by British Aerospace.
