Overview
Taylor Hobson is a British precision measurement and metrology company based in Leicester, England. Founded in 1886 by optician Thomas Smithies Taylor and engineer William Taylor, the business began by manufacturing optical lenses and later became associated with the Cooke name. Its early work combined optical design with the development of specialized machinery for producing and inspecting lenses, establishing a technical culture centered on measurement, surface quality, and manufacturing accuracy. The company’s original optical activities expanded during the late nineteenth and early twentieth centuries. W. S. H. Hobson joined the business in 1887, helping develop its commercial identity as Taylor, Taylor & Hobson. The company produced its first Cooke lens in 1893 under an arrangement involving T. Cooke & Sons of York, and later developed international connections, including a New York branch opened by J. Ronald Taylor in 1902. During the First World War, Taylor Hobson contributed optical products and manufacturing expertise to aerial photography and military applications. Its work included lenses for binoculars, range finders, gun sights, rifle bores, and telescopes, as well as machinery for accurately polishing optical components. A defining strategic shift emerged from the company’s need to control the quality of its own lenses. William Taylor developed instruments to assess surface texture and roundness, initially treating them as internal production tools. Demand from other manufacturers eventually led Taylor Hobson to commercialize these instruments. This transition turned the company into an important supplier of industrial metrology equipment and laid the foundation for its modern business. Taylor Hobson introduced the Talysurf 1 in 1941, described as the first true surface texture measuring instrument, and followed it with the Talyrond 1, an early roundness measuring instrument, in 1949. Subsequent products addressed shop-floor roughness testing, ultra-precise step-height measurement, form measurement, cylindricity, contour, and three-dimensional surface analysis. The company’s instruments have been used in sectors where small deviations in geometry or surface finish can affect performance, including precision engineering, automotive manufacturing, aerospace, optics, semiconductor production, and research. The business continued to evolve through acquisitions, software partnerships, and new measurement technologies. It became part of the Rank Organisation in 1946, acquired Hilger and Watts in 1969, and was purchased from Rank by Schroder Ventures in 1996. Its historical Cooke lens business was separated in 1998 through a transaction that created Cooke Optics. In 2004, Taylor Hobson joined AMETEK’s Ultra Precision Technologies Group, where it remains associated with high-accuracy measurement and manufacturing technologies. Today, Taylor Hobson is principally known for metrology rather than consumer optics. Its portfolio includes stylus and optical profilometers, roughness testers, form and contour systems, roundness and cylindricity instruments, and analysis software. The brand’s positioning is based on high precision, repeatability, traceable inspection, and the integration of measurement into production and quality-control workflows. Its products range from portable or shop-floor instruments to highly automated systems for inspection laboratories and advanced manufacturing environments.
History
Taylor Hobson was established in Leicester in 1886 as T. S. and W. Taylor by brothers Thomas Smithies Taylor and William Taylor. The founders brought complementary skills in optics and engineering, initially concentrating on the manufacture of lenses. The enterprise later moved from Slate Street to Stoughton Street Works, where it developed a broader industrial base. W. S. H. Hobson joined in 1887, and the business became known as Taylor, Taylor & Hobson, commonly abbreviated as TTH. The company’s early growth was closely linked to optical technology. In 1893 it began producing Cooke lenses under an arrangement connected with T. Cooke & Sons of York. A New York branch opened in 1902 under J. Ronald Taylor, with Eastman Kodak among its principal customers. By the early twentieth century, Taylor Hobson’s activities included photographic lenses, optical goods, engraving machinery, fine tools, golf-ball moulds, and time-recording equipment. It also licensed a typeface template to the George Gorton Machine Company in 1895; the resulting Gorton lettering system became widely used for engraved signs. Military and industrial requirements during the First World War accelerated the company’s optical capabilities. Taylor Hobson developed Aviar lenses for aerial photography and manufactured lenses and equipment for binoculars, range finders, gun sights, rifle bores, and telescopes. Its lens-polishing machinery helped support larger-scale production. William Taylor received an OBE in 1919, and the company hosted a royal visit that year. In the interwar period, it continued optical innovation, producing an early Cooke cinematography zoom lens in 1932. By 1939, the company was reported to supply more than four-fifths of lenses used by film studios. The origins of Taylor Hobson’s metrology business arose from the demands of lens manufacturing. William Taylor believed that superior optical products required unusually precise knowledge of surface quality and roundness. He therefore developed instruments to inspect these characteristics. Although the company initially kept the devices for internal use, other manufacturers sought similar equipment, eventually persuading Taylor Hobson to commercialize the technology. The Talysurf 1, introduced in 1941, became a landmark surface-texture instrument, followed by the Talyrond 1 in 1949 for roundness measurement. After becoming part of the Rank Organisation in 1946, Taylor Hobson expanded its measurement portfolio. Its developments included a micro-alignment telescope in 1951, the portable Surtronic roughness range in 1965, and the TalyStep system in 1966 for very precise step-height measurement. The acquisition of Hilger and Watts in 1969 broadened the company’s optical and measurement capabilities. In 1984, the Form Talysurf combined millimetre-scale form measurement with nanometric resolution, allowing form and roughness to be assessed in a single system. The company received a Queen’s Award for technological achievement in 1992. During the 1990s it introduced the TalyScan 3D contact scanner and the Form Talysurf PGI, which used phase-grating interferometry to achieve sub-nanometre height measurement. It also adopted Digital Surf’s Mountains software technology, supporting the development of TalyMap and TalyProfile analysis environments. In 1996, Schroder Ventures acquired Taylor Hobson from Rank. Taylor Hobson’s historic lens business separated from the company in 1998 through a buyout that created Cooke Optics. The remaining business increasingly focused on industrial metrology. It introduced the TalySurf CCI optical field profiler in 2003, joined AMETEK’s Ultra Precision Technologies Group in 2004, and continued developing automated and multi-parameter inspection platforms. The TalyRond 395, launched in 2007, supported automated roundness and cylindricity measurement. Later launches included the CCI Lite, Talyrond 290, Talymaster, CCI MP, CCI HD, and successive Surtronic and Talyrond systems. Taylor Hobson now operates as an AMETEK brand focused on precision inspection and measurement for advanced manufacturing.

Products and positioning
High-precision industrial metrology for surface texture, form, roundness, optical surfaces, and automated inspection.
Surface texture and form metrology · 1941
Talysurf
Talysurf is Taylor Hobson’s principal family of surface texture and form measurement systems. The range developed from the Talysurf 1, introduced in 1941, into systems capable of assessing roughness, waviness, contour, and larger-scale form with very high vertical resolution. Depending on configuration, Talysurf instruments use stylus or optical measurement principles and can support laboratory inspection, production engineering, and advanced surface characterization.
Portable roughness measurement · 1965
Surtronic
Surtronic is a family of portable and shop-floor roughness testers. Introduced in 1965, the range emphasized practical deployment by using a skid pickup that follows the general surface form while allowing straightforward assessment of roughness. Later Surtronic generations expanded the range for industrial inspection and included R50, R80, and R100 series instruments.
Roundness and cylindricity metrology · 1949
Talyrond
Talyrond systems measure roundness, cylindricity, and related geometric characteristics. The Talyrond 1, introduced in 1949, established Taylor Hobson’s long-running presence in roundness measurement. Later systems, including the automated Talyrond 395 and motorized Talyrond 290, were designed to improve repeatability, automate inspection sequences, and support use in both laboratories and manufacturing environments.
Three-dimensional surface scanning · 1995
TalyScan
TalyScan systems provide three-dimensional surface texture measurement using contact scanning arrangements. The original TalyScan introduced in 1995 had a compact, computer-mouse-like form, while later versions used more conventional motion stages. The family extended Taylor Hobson’s surface metrology portfolio beyond line-based profiles toward areal characterization.
Ultra-precision form measurement · 1996
Form Talysurf PGI
The Form Talysurf PGI was introduced in 1996 as a high-accuracy form and surface measurement system. It used a phase-grating interferometer height-sensing principle to achieve sub-nanometre accuracy while retaining contact measurement characteristics. This approach made the system useful for demanding surfaces whose optical properties could complicate purely optical inspection.
Optical 3D profiling · 2003
CCI
The CCI family brought optical, microscope-based field profiling into Taylor Hobson’s portfolio. Introduced in 2003 and later expanded through CCI Lite, CCI MP, and CCI HD variants, the systems complement stylus and scanning profilers with non-contact three-dimensional measurement. They are intended for detailed characterization of surfaces where optical inspection provides advantages in speed, coverage, or contact-free measurement.
Step-height measurement · 1966
TalyStep
TalyStep was introduced in 1966 for ultra-precise measurement of step height using very low contact forces. It became associated with the emerging semiconductor industry, where small vertical differences and delicate structures required sensitive measurement. The system illustrates Taylor Hobson’s expansion from optical inspection into specialized dimensional metrology.
Automated inspection · 2009
Talymaster
Talymaster is an automated inspection concept launched in 2009. It combines roughness, roundness, and contour measurement within a single inspection workflow, reducing the need to move components between separate instruments. The product reflects Taylor Hobson’s strategy of integrating several geometric and surface characteristics into production-oriented automated systems.
