The Photonics Leadership Group is updating it list of UK photonics companies in preparation for updating the size 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
Note this list includes companies directly involved in photonics and the immediate supply chain. Not all of these will be considered as having a direct photonics contribution and in many 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 from completeness, but are not considered as a direct part of the industry.
