Cooke Optics Ltd. is a camera lens manufacturing company based in Leicester.
The foundation of Cooke Optics is coincident with Taylor, Taylor and Hobson (TTH) in 1886, as the sole activity of TTH was the manufacture of lenses under the Cooke branding. Administratively speaking, Cooke Optics is a spin-off of Taylor-Hobson, created after Taylor-Hobson shifted its focus to metrology instruments.
The brand name Cooke originally came from the company T. Cooke & Sons of York, a manufacturer of telescopes. The optical manager of that company, H. Dennis Taylor (no relation), devised the Cooke triplet lens in the 1890s. Cooke of York was not interested in the manufacture of camera lenses, and licensed this design and others to TTH. Subsequently many of TTH's own designs, though unconnected with Cooke of York, also carried the Cooke brand. The Cooke triplet lens was also made under licence by Voigtländer and other companies.
Throughout the twentieth century TTH produced a series of innovations, and supplied lenses for the (once large) UK camera industry, for photolithography in the printing industry in the USA and UK, and for cinematography. It provided a succession of technical solutions for Hollywood's evolving needs.
Bell & Howell took control of the company in 1930, but it was sold to Rank in 1946. In its later years, Taylor-Hobson's main interest was metrology, and it now operates as a subsidiary of Ametek.
In 1998, Cooke Optics was a new company formed following a buy-out of the Optical division of Taylor-Hobson. Chairman Les Zellan led the buy-out. Dave Stevens was then Managing Director of the Leicester-based facility and remained so until 2008 when Robert Howard replaced him as Chief Executive Officer. In 2018 Cooke Optics was acquired by Caledonia Investments. In 2020 Cooke announced the appointment of Tim Pugh as Chief Executive Officer and Kees van Oostrum as Non-Executive Chairman.
The company now designs and manufactures 35 mm lenses for the film industry. In a reversion to its previous markets, it has also made limited quantities of the PS945, a redesigned Pinkham and Smith portrait lens, [1] and the Series XVa, a redesigned triple-convertible lens for 10×8 inch format. The company distributes to over 60 countries worldwide and exports 90% of its production.
In 2013, the Academy of Motion Picture Arts and Sciences gave the company an award of merit, saying it "helped define the look of motion pictures over the last century," with innovations over the years that have included zoom lenses for movie cameras and lenses that did not require bright lights. resulting in lenses that produce what is known in the industry as the "Cooke look" — warm, natural images on the screen.

Notable products include:
A camera lens is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
The Cooke triplet is a photographic lens designed and patented in 1893 by Dennis Taylor who was employed as chief engineer by T. Cooke & Sons of York. It was the first lens system that allowed elimination of most of the optical distortion or aberration at the outer edge of the image.
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses, although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group.
The Angénieux retrofocus photographic lens is a wide-angle lens design that uses an inverted telephoto configuration. The popularity of this lens design made the name retrofocus synonymous with this type of lens. The Angénieux retrofocus for still cameras was introduced in France in 1950 by Pierre Angénieux.
Carl Zeiss AG, branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe and Otto Schott he laid the foundation for today's multinational company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue in almost 50 countries, has 30 production sites and around 25 development sites worldwide.
The Tessar is a photographic lens design conceived by the German physicist Dr. Paul Rudolph in 1902 while he worked at the Zeiss optical company and patented by Zeiss in Germany; the lens type is usually known as the ZeissTessar. Since its introduction, millions of Tessar and Tessar-derived lenses have been manufactured by Zeiss and other manufacturers, and are still produced as excellent intermediate aperture lenses.
A zoom lens is a system of camera lens elements for which the focal length can be varied, as opposed to a fixed-focal-length (FFL) lens.
Voigtländer was a significant long-established company within the optics and photographic industry, headquartered in Braunschweig, Germany, and today continues as a trademark for a range of photographic products.
A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics). Catadioptric combinations are used in focusing systems such as searchlights, headlamps, early lighthouse focusing systems, optical telescopes, microscopes, and telephoto lenses. Other optical systems that use lenses and mirrors are also referred to as "catadioptric", such as surveillance catadioptric sensors.
The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1929 and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture.
Ophir Optronics Solutions is a multinational company that sells optronics solutions. The company develops, manufactures and markets infrared (IR) optics and laser measurement equipment. Founded in 1976, the company was traded on the Tel Aviv Stock Exchange from 1991 until it was acquired, and was a constituent of its Tel-tech index. Headquartered in the Har Hotzvim industrial park in Jerusalem, Israel Ophir owns a 100,000-square-foot (9,300 m2) complex that includes the group's main production plant. Ophir has additional production plants in North Andover, Massachusetts and Logan, Utah in the US and sales offices in the US, Japan and Europe. In 2006, Ophir acquired Spiricon Group, a US-based company in the beam-profiling market. Ophir's sales increased sharply from $45 million in 2005 to $74 million in 2007. During 2007, Ophir established a Swiss-based subsidiary to market lenses and components for surveillance and imaging systems in Europe. In May 2010, Ophir acquired Photon Inc., another US-based beam-profiling company. Newport Corporation, a global supplier in photonics solutions, completed its acquisition of the Ophir company in October 2011. In 2016, metrology firm MKS Instruments bought Newport Corporation, including the Ophir brand, for $980 million.
A dialyte lens is a compound lens design that corrects optical aberrations where the lens elements are widely air-spaced. The design is used to save on the amount of glass used for specific elements or where elements can not be cemented because they have dissimilar curvatures. The word dialyte means "parted", "loose" or "separated".
An anastigmat or anastigmatic lens is a photographic lens completely corrected for the three main optical aberrations: spherical aberration, coma, and astigmatism. Early lenses often included the word Anastigmat in their name to advertise this new feature.
Nikon F 80-200mm lens refers to several generations of single-lens reflex telephoto zoom lenses for made by Japanese camera manufacturer Nikon.
Ludwig Jakob Bertele was a German optics constructor. His developments received universal recognition and serve as a basis for considerable part of the optical designs used today.
Taylor Hobson is an English company founded in 1886 and located in Leicester, England. Originally a manufacturer of still camera and cine lenses, the company now manufactures precision metrology instruments—in particular, profilometers for the analysis of surface textures and forms.
The invention of the camera in the early 19th century led to an array of lens designs intended for photography. The problems of photographic lens design, creating a lens for a task that would cover a large, flat image plane, were well known even before the invention of photography due to the development of lenses to work with the focal plane of the camera obscura.
Mr. Jun Hirakawa(平川純) is a Japanese lens designer best known for creating the Pentax FA 43mm Limited and FA 77mm Limited lenses during his time at Pentax.
Huawei P40 is a line of high-end Android-based smartphones manufactured by Huawei. Unveiled on 26 March 2020, they succeed the Huawei P30 in the company's P series line.
Horace William Lee was an optical designer responsible for developing multiple influential lens designs, including the Opic (1920), an asymmetric large-aperture double Gauss lens, and the inverted telephoto wide-angle lens (1930), while working for the English optics firm Taylor, Taylor & Hobson (TT&H), which manufactured lenses in Leicester under the Cooke brand. Lee's designs helped to develop the modern cinematography industry, with high-speed lenses enabling sound synchronization, and the inverted telephoto providing enough space for a beam-splitter apparatus to capture color.
