The Photonics Leadership Group maintains a list of all UK photonics companies as a basis the sizing of the UK Photonics industry. Please review the list below and contact us with any omissions including company name, registered company number and operating / manufacturing location using the form below. Updates are processed in batches and there may be a delay in submissions appearing
Note this list includes companies directly involved in photonics and the immediate supply chain. Many of them are highly diversified, producing many other products and in those cases only a fraction of their output will be counted toward the UK photonics industry. There are also examples of suppliers to, and users of, photonics that are retained for completeness, but are not considered as a direct part of the industry.
Note companies can appear more than once for each regional location we have on file for them, this enables accurate regional filtering. Universities and government funded organisations will be added shortly
