The maker of a thermal imaging camera used to "great effect" by firefighters at the Buncefield depot explosion has predicted further strong growth.
E2V, which employs 1,300 people, said a record order book of £91.5 million - 23 per cent higher than a year earlier - suggested progress would be made in the new financial year.
It said its firefighting business was expected to benefit from the launch of a new version of its Argus camera, following the success of a previous version used to pinpoint heat sources in December's Buncefield blaze.
Technology enabling dentists to capture digital images of teeth is also expected to be another growth area for the company in the year ahead.
E2V also makes sensor technology for use in military surveillance and radar, while it has also supplied imaging parts for the Hubble telescope.
Growth in the past year has come from the medical and science arm of its sensors business, which increased sales by 34 per cent to £20.7 million.
Overall, revenues were up 11.7 per cent to £112.3 million with profits ahead 39.4 per cent to £13.6 million in the year to March 31. Chief executive Keith Attwood said: "Our record order book suggests continued positive progress through the current financial year, despite the pressures of rising input costs, particularly in energy and materials."
The company, which was once part of GEC, did however struggle with rising energy and materials costs.
Mr Attwood said: "We are a very energy intensive business, our electricity costs rose by 40 per cent in October and by another 30 per cent in April. It is a big issue for us, so we have brought in a professional specialist to negotiate the best deals for us.
"But it is not just about the price of energy, we are working to reduce our usage, and our energy use in absolute wattage is coming down."
Mr Attwood added the company ' s research and development effort would continue, with around £5.3 million spent last year and £ 10 million overall including joint work with customers.
He said: "Research and development is very important to the company and we expect to spend more than that this year. This will involve long term projects rather than just adapting products to customer's specifications."
