History of Technical Innovation, Service & Quality in Thermal Imaging







Thermoteknix was founded in 1982 and has a distinguished history of consistent technical breakthroughs in infrared (IR) thermal imaging and thermal measurement based hardware, systems and software application products. Recognized in 1998 by the prestigious ‘Queen’s Award For Export Achievement,’ the ‘Queen’s Award for Enterprise (Innovation)’ in 2008, then again in 2015, Thermoteknix is one of the world’s leading sources of thermal imaging expertise and excellence.

“What drove you to form Thermoteknix in 1982 in such a technically challenging and cut-throat market with large multi-national corporations as your main competitors?”






“Thermal Imaging technology today is a mature science but in 1982 it was in its infancy. Back then, thermal imaging equipment was very large and heavy and the computer systems powerful enough to process real time video data and imagery only existed in Ministries of Defence. Such technology was certainly not commercially available to the scientific community, industrial monitoring nor law enforcement markets. At that time I was a physician specialising in Rheumatology at Cambridge, with both clinical medicine and academic research posts.

“We recognised the need for a computerised thermal imaging system to quantify inflammation, assess response to therapy and prevent long term damage to diseased joints. I had previous experience in this area having been a doctor at the Royal National Hospital for Rheumatic Diseases in Bath which was a leader in medical thermal imaging at the time. In collaboration with computer scientist Mike Prees, we put together a computerised hardware and software processing system for thermal imagers and realised that it had wider applications outside the field of our immediate use. We contacted Agema in Sweden, who were the manufacturers of the Thermovision 680 – the thermal camera we had already interfaced to our own designed digital electronics and processing software, which was then operating on an Apple II/CPM micro-computer. Agema recognised the potential of our technology for their customers and we formed Thermoteknix in order to commercialise and OEM the product to them for their global customer base.

“The “PC” market was developing rapidly and we saw the need to develop our technology into real-time video based image processing and to move the platform onto IBM PC/Intel technology. Our state-of-the-art electronics and software were ideally suited to the needs of another US infrared camera manufacturer, Inframetrics Inc, and we supplied them exclusively as an OEM with our wide range of Scientific, Military and Predictive Maintenance digital
hardware and software products. This arrangement endured successfully for 12 years until 1998, when FLIR purchased Inframetrics. Some years prior to this, we realised that reliance on a single customer and route to market embodied significant commercial risk and limitation to the company’s growth. We therefore needed to broaden the Thermoteknix portfolio by developing a range of vertical market products with our own routes to market.

“Early IR instruments were created by mechanically skilled developers in many companies yet they lacked the data capture electronics and software analysis tools needed to obtain the best value from the IR data generated by their instruments. With our unique experience and insight into the science of image processing, signal analysis and industry software standards, Thermoteknix developed TherMonitor® Reporter and ThermaGRAM® electronic hardware and software in the early 1980’s. We marketed them in partnership with leading IR camera suppliers for the next 20 years. Those products have become the ‘de facto’ IR industry standard tools and helped Thermoteknix’ marketing partners become the largest camera and systems suppliers of their time.”

“Was the defence and law enforcement market the key driver then?”

“No, defence and law enforcement markets came later with the development of our own thermal imaging cameras and modules. The scientific community was the main driver for our original OEM imaging market products with a focus on Research and Development, subsequently Predictive Maintenance and then Defence and Security. Running parallel to that was the development of a range of industrial thermal cameras built for continuous operation in the cement industry. These cameras must operate 24 hours per day, 365 days per year in very challenging environments, subject to extreme weather conditions and exposed to high levels of dust, shock and vibration. Thermoteknix have now sold over 1000 systems in more than 50 countries around the world. Having created camera systems which survive outdoors in severe conditions, (-40°C to + 60C and up to 1200°C inside a cement kiln) we now had the experience needed to design, build, supply and support thermal imaging solutions for a number of other sectors. These included security, surveillance and defence where durability, robustness, miniaturisation and unfailing reliability are all essentials.”





“Recognising the ability of our products to withstand extreme heat and vibration, Formula 1 were interested in using our technology to record and manage on track tyre temperature and heat distribution – a factor critical to performance. In 2008, we were contracted to develop a real-time miniature thermal imaging camera suitable to be installed on F1 race cars to monitor tyre temperature during testing and race practice. The data recorded by cameras enabled F1 team engineers to make adjustments to the suspension and other componentry to optimise traction and handling. This huge success was followed by a project with Red Bull Racing who wanted a similar system for their IndyCar team. This led to our big break with Johns Hopkins Applied Physics Lab who were working with CISCO to install systems on helicopters and Rapid Response vehicles. The team were also working on the Aegis Anti-Balistic Missile Defense system and we became a key supplier with our miniature thermal imaging cameras being used onboard for Aegis missile tests.

“Then came our most significant and prestigious contract to date which was working with NASA on the LCROSS (Lunar Crater Observation and Sensing Satellite) program, a complex mission to confirm the presence of sub-surface water on the Moon. We developed and supplied a space certified miniature thermal radiometric camera which was installed onto the Lunar robotically controlled spacecraft to film the debris and material resulting from the impact when the Centaur upper stage booster was deliberately driven from space into the Lunar surface. Analysis of the resulting plume conclusively proved the presence of lunar sub-surface water ice. We were the only non-US company selected for the LCROSS sensor project and we also captured the first and only thermal images of the dark side of the Moon. It was a truly exhilarating moment when five of our Thermoteknix team attended NASA Ames Mission Control during the closing stages of the LCROSS mission to witness the impact of the Centaur rocket booster into the Moon and the thermal images captured by our camera following six minutes behind in its wake. We are also proud to have one of our thermal imaging cameras now permanently embedded in the Moon!”

“In 2004 FLIR purchased another key infrared camera manufacturer Indigo Systems. Indigo were an OEM customer of ours and we saw the need to drastically redirect our business. This was to take into account the growing trend to online sales and the companies like FLIR developing very broad product ranges to address the industrial, law enforcement and military markets.

“Our new strategy was to restructure the Thermoteknix product offering into three related yet separate market sectors:
Industrial systems, OEM thermal imaging cores and modules, and Security, Surveillance and Defence vertical market products. Our aim was to develop a range of leading technology, non-ITAR, low power, high performance, cost effective products incorporating the best Size, Weight and Power (SWaP) combined with our proven expertise in quality, reliability, customer support and service.”
Segment Breakdown
Industrial – 30% with 10% compound growth p.a.
OEM Cores (Defence) – 30% with 10% – 30% compound growth p.a.
Security, Surveillance and Defence – 40% with 15% – 20% compound growth p.a.”

ClipIR Small Clip-On Thermal Imager – Fused Thermal and Night Vision






The Thermoteknix ClipIR is a miniature self-contained uncooled thermal imager which attaches directly to most monocular, bi-ocular or binocular Night Vision Goggles (NVG’s) to deliver fused thermal and night vision when required. This extends and improves operational capabilities in all dark and low light conditions by providing enhanced situational awareness and threat identification. Fused thermal imaging and night vision synergistically increase engagement capability for the dismounted fighter. This is particularly important in urban environments, in buildings, caves or on jungle missions where intensifiers alone cannot deliver operational effectiveness due to limitations of NVG functionality in such situations.

ClipIR – with patented Shutterless XTI Technology® is the only clip-on thermal imager with a real-time 40° Field of View fused image. Small and weighing only 150g, with 4½ hours battery life from 1xAA battery, ClipIR is a compact, powerful addition for every NVG.

The Future

Thermoteknix currently employs 69 people at its Cambridge facility with agents representing their products all over the world. Many of these agents are highly qualified engineers with a breadth of capabilities from embedded and UI software through microelectronics in thermal imaging.

“How do you see Thermoteknix in the next twenty years?”

“My co-founder, Mike Prees, retired in 1992 and Thermoteknix has been family owned since then with my wife Geraldine as co-director. We currently turn over between £10-12m per annum without external investment. We have a history of innovation, recognised by three UK Queen’s Awards, technology development unsurpassed in the industry and a reputation earned over thirty years for quality and customer dedication by our long serving, and extraordinarily gifted staff. We work closely with our agents on the ground and we have products in use and still supported for more than twenty years. I am indebted to my wife and co-director, Geraldine who has shared the trials and tribulations and successes of our Company since its inception and to our children who have been part of our journey into the dark. I would obviously like one or more of our sons to take a role in driving the business forward in the future and to bring their energy and skills to grow and adapt the direction of the company. Finding the best staff is always challenging and the current Brexit debacle is a real obstacle to recruitment with its negative climate for stability, investment and business development. The sooner the UK’s position and role on the world’s stage are confirmed and agreed, the better it will be for UK PLC.”

“In the military product segment our mission is to develop and deliver a range of products extending from a simple sensor for the dismounted war fighter to a variety of sophisticated multi-function devices integrated across the battlefield and to the HQ.”

Dr Richard Salisbury, aged 69 has been married to Geraldine for 32 years. They have four boys, Max, an A&E doctor, Jonti, territory sales manager at Thermoteknix, Ben, European sales manager at the London Stock Exchange, FTSE Russel Group, and Charlie who is a data analyst at the Chicago Mercantile Exchange
