This Cambridge company manufactures thermal imaging systems for industry, defence and security. Its products include clip-on thermal imagers with Augmented Reality for night vision army goggles, and fever screening and face mask detection technology, developed in response to the pandemic. In 2009, it supplied its space qualified thermal imaging camera for NASA’s LCROSS satellite, which identified the presence of sub-surface water on the moon – other applications include F1 racing and TV wildlife. Thermoteknix generated more than 90% of its £15.8m sales overseas in 2021. This year marks the business’ fortieth anniversary, which was founded in 1982 by managing director Dr Richard Salisbury.
