Teledyne e2v is a global leader in specialised components and subsystems for innovative solutions in medical, science, aerospace, defence and industrial applications.

Teledyne e2v have a track record of producing innovative technologies and products, such as critical components of radiotherapy machines and space-based sensors that monitor global warming and pollution.

Previously known as e2v technologies, the company was acquired by Teledyne Technologies Inc. in March 2017.

Based in Chelmsford for over 70 years, Teledyne e2v’s Chelmsford facility is Teledyne’s largest location outside of North America.

New Teledyne e2v products and technologies

Teledyne e2v’s products include solutions for advanced image sensors and cameras for applications such as industrial process control (monitoring and cooling of machinery), dental X-ray systems, life sciences, space science, astronomy and Earth observation.

The manufacturing activities at the Chelmsford facility include specialist Charge Coupled Device (CCD) image sensors that go into the major space programmes of the world along with the development of next generation complementary metal–oxide–semiconductor (CMOS) image sensor technology.

Another key manufacturing activity is the production magnetrons and thyratrons for radiotherapy machines and modulators and providing Radio Frequency (RF) products for a host of other applications from defence and military systems to telecommunications.

Teledyne e2v employs more than 900 people in Chelmsford alone – with a large base of scientists and engineers. Teledyne e2v also has facilities in Lincoln, France, Sweden and Spain and sales offices in Asia and USA.

Leaders in the global hi-tech market

Teledyne e2v’s Chelmsford facility is a constant source for the development of new products and new technologies and leads in its chosen market. For example, in the field of radio frequency (RF) power products, a very high proportion of the world’s radiotherapy machines use Teledyne e2v’s magnetrons.

The AEOLUS satellite, which launched in August 2018, is designed to improve weather forecasting; in which the sensing instrument contains an ultraviolet detector made by Teledyne e2v in Chelmsford.

Quantum and Aerospace Technologies

The Teledyne Chelmsford facility is also leading globally in the innovative field of quantum technologies; a key technology and capability for the UK identified by the government, for which the company is receiving funding from Innovate UK.

Teledyne e2v also recently announced the development of the ultra-precise atomic iqClock. As a member of the European Quantum Technologies Flagship, the iqClock will be one of the first 20 projects to be funded by the European Commission and aims to make highly accurate atomic clocks portable and commercially viable using a new technology called the ‘superradient laser’.

Other Quantum technology developments at the Chelmsford facility include gravity sensing devices and the development of cold atom test systems in space. The company is working towards a commercial satellite unit that contains a Cold Atom Space PAyload (CASPA).

One prominent example of a recent high-profile Teledyne e2v initiative in space is PLATO (Planetary Transits and Oscillations of stars), a planet hunting spacecraft that will seek out and research Earth-like exoplanets around stars similar to our own Sun. About 100 Teledyne e2v large area Charged Couple Devices (CCD) will allow the mission to detect small changes in the apparent brightness of stars orbited by planets.

Another major project is GAIA – an ambitious mission to chart a three-dimensional map of the Milky Way in an attempt to process and reveal its composition, formation and evolution. As with PLATO, all of the GAIA CCD image sensors will be designed and produced in the UK at the Teledyne e2v Chelmsford facility.

Continuing to push the boundaries of sensing technology

Looking to the future, as Teledyne e2v continues to invest in keeping their technology relevant and cutting edge, so they expect to further grow and develop. Ground-breaking programmes like ESA’s Copernicus and future missions from other national space agencies will allow for them to constantly push the boundaries of what is possible in the vital field of sensing technologies.
