The pleasure was made greater by a display of Press Releases and articles some of which the Editor had written as a consultant to the then Pilkington Optronics in the 1980s at the start of this journey to 40 years. One tinge of sadness was a photograph of Pilkington PR supremo Roy Jones, with whom the Editor worked at Pilkington for many years. Sadly Roy died at an early age after an early retirement from the Company. One of the displays showed the Infrared Search and Track (IRST) module for which the Editor wrote the original Press Release when this system was launched in 1988!
Qioptiq were not only celebrating 40 years of continues support to the British Armed Forces they also signed the Armed Forces Covenant with MG Paul Jacques, CBE, Director Land Equipment and the formal signing of the Gold Sponsorship of Team Army with MG Lamont Kirkland CBE and Lt. Co. (Retd.) Tim Wakefield.
Craig Taylor of Qioptiq introduced a group of speakers from the Company who gave a number of presentations.
Steve Shaw, Senior Vice President of the Defence and Aerospace Division gave an update on the current structure of Qioptiq’s defence activities following the purchase by Excelitas from Candover in 2013.
“Leading the world in expertise and facilities, Qioptiq is a recognized, first-tier supplier to many of the defense and aerospace sector’s leading companies. We have a complete offer of components, modules, technology and equipment for defense and aerospace applications.” Steve Shaw said.

Qioptiq’s glass compositions and custom coating designs have made the Company the major global supplier of both solar cell coverglass and optical solar reflectors to the global space industry. Qioptiq Space Technology supplies more than 80% of global demand for solar cell cover glass and optical solar reflectors (OSR).
Silicon solar cells and Gallium Arsenide solar cells
Qioptiq has developed and qualified a wide range of coatings for both Silicon solar cells and Gallium Arsenide solar cells, and we have an excellent optical solar reflector offer for thermal control applications.
Infrared systems components
Infrared systems components are used in equipment designed to detect and track any kind of thermal targets, including missiles, tanks, armored vehicles, helicopters and fighters, for situational awareness or to detect threats related to thermal light emission. Qioptiq’s expertise also has commercial applications and is used, for example, in lenses for thermal inspection systems.
To demonstrate the success components business Peter White of Qioptiq later said that Qioptiq’s components modules were in the US Thermal Weapon Sights (TWS) with 75,000 Qioptiq sights in service around the world. In addition Qioptiq is the supplier for optical modules for key armoured vehicle Programmes and Remote Weapons Stations (RWS) for a variety of manufacturers.
Typical components for infrared applications are, Optical components for missile warning, detection and tracking systems; Missile seeker head components and modules; Components for thermal surveillance and inspection cameras; Spherical and aspheric lenses; Mirrors and prisms; Domes and windows; Cassegrain systems and Optical components and assemblies for SWIR, MWIR and LWIR wavebands.

History of Qioptiq
Martin Adams, Director Land Equipment, a veteran employee of Qioptiq, celebrating 25 years with the Company was well paced to give a history of how the Company was formed by the Pilkington and Greenall families in 1840 to the purchase of Close Brothers in 1951 with the subsequent move to St Asaph in 1957, the JV with Perkin Elmer which formed Pilkington PE, the purchase of Barr & Stroud in 1974, the Thorn EMI purchase, which enabled the IRST development, the formation of Pilkington Optronics in 1988, the purchase by Thomson-CSF in 1990, moving into Thales with the 10% MoD stake disposal, the purchase of Avimo in 2000, the sale to Candover in 2005 to the 2013 acquisition by Excelitas.
The mention of the 1988 formation of Pilkington Optronics was the Editor’s first major exercise in rebranding. Pilkington Corporate had drawn up a comprehensive rebranding document which required every Pilkington defence and aerospace facility to be branded Pilkington Optronics, dropping the PE from Pilkington PE and calling Barr & Stroud Pilkington Optronics. Barr & Stroud was established in 1888 at the Anniesland, Glasgow facility. Glaswegians are quite rightly proud of their Scottish Industrial Heritage so were stubbornly resisting any change! The transition at the St. Asaph facility was smooth and painless with name boards and notepaper headings being changed and telephone receptionists answering “Pilkington Optronics, can I help you?” The stubborn Glaswegians had other ideas! After Roy Jones and the Editor visited the facility to brief the late great, PR Supremo Christine Keddie and her staff on the rebranding exercise, they were met by a moot acceptance of the document and the Corporate changes required.
We both left feeling that the message had not or would not get through! We were right, it took another six months and a lot or gentle persuasion to persuade the telephone receptionist from saying, “Barr & Stroud, can I help you?” to “Pilkington Optronics, can I help you?” along with the general acceptance that sadly the great name of Barr & Stroud had been consigned to history. The move from Anniesland to the new site under Thales eased this process through another rebranding exercise which the Editor was not involved with, Tim Orr had to take up the cudgels for that!
Steve Rickard, Business Product Development Manager Land then gave an update on Qioptiq’s product development and R&D activities.
“We regard product development and R&D as key to our goal in being a world leader in optical technology, excellence is embodied in all we do.” Steve Rickard said. “Qioptiq is involved in a number of development projects, either jointly or sole funded, with the MoD, DSTL and a number of key Universities. We also work with our partners and Primes in product development and enhancement. We routinely spend 6% of our revenue on R&D, most of which is in the UK. As well as R&D we see continued through life support as key to our success.”
This was later supported by Steve Shaw who saw a consolidation coming in the industry with the strongest surviving being those with the best technology, export markets, price and customer support,
Steve Rickard outlined a number of key technologies Qioptiq was developing including, image fusion, visible IR, SWIR, dismounted helmet displays, 12 micron-based products which he expects to launch within 12 months and IR Chalcogenides, a new technology.
Wikipedia describes Chalcogenide glass as a glass containing one or more chalcogenide elements (not counting oxygen). The name chalcogenide originates from the Greek word ‘chalcos’ meaning ore and ‘gen’ meaning formation, thus the term chalcogenide is generally considered to mean ore former. These are three elements in Group 16 in the periodic table: sulphur, selenium and tellurium. Such glasses are covalently bonded materials and may be classified as network solids; in effect, the entire glass matrix acts as an infinitely bonded molecule. Although Polonium is chemically a chalcogenide as well, it is not used in chalcogenide glasses because of its strong radioactivity and high price. Oxygen is also a group 16 element, but it is not considered a chalcogenide. Though oxide materials are the oldest known glass forming systems it has become more traditional to treat them separately from more recently discovered chalcogenide compounds. Scientifically oxide materials behave rather differently from other chalcogenides, in particular their widely different band gaps contribute to very dissimilar optical and electrical properties. Chalcogenides can exist naturally as minerals; two of the most well-known being FeS2 (pyrite) and AuTe2 (calaverite).
It was fitting that Qioptiq should celebrate 40 years alongside SS Great Britain, one of Brunel’s great engineering marvels and still proudly moored at its 1843 launch dock in Bristol.
Certainly the briefings Qioptiq gave and the history of the Company from its early incarnations made the Editor proud to have been associated with the business as PR and Press and saw a huge and prosperous future for Qioptiq and the UK’s advanced engineering technology base.
