In 1975 Dorsey purchased the instrument division of the Hamilton Watch Company of Lancaster, Pennsylvania. This acquisition added the well-known and respected Hamilton-Datcon dial indicator instruments to the Company’s products. During 1976 Dorsey relocated to the 35,000 square foot building at 253 Mansion Street in the City of Poughkeepsie, New York. In 1986 Dorsey Gage acquired Pexit, an English company known throughout Europe and Asia for their high quality, precision optical comparators. The design and facilities of Pexit were relocated to Poughkeepsie, New York, where it became the Optical Metrology Division of Dorsey Gage. Since its inception, the Optical Metrology Division has adapted the Dorsey philosophy of providing a top quality inspection instrument that exactly matches the customers’ requirements. Throughout this entire development of the Dorsey family of inspection products, the company also continued the sale of their craftsman services. These services included: instrumentation, contract machining, inspection, automation and the manufacture of special tooling and equipment. While catering to a variety of companies, their most prominent customer was IBM Corporation; the area’s largest. It was through these efforts that Dorsey Gage Company became involved in a project known as the electrostatic chuck program.
