Covesion started trading in 2009 as a spin-out company from Stratophase Ltd. & the University of Southampton

Our team of poling experts have over 10 years experience in the manufacture of PPLN for off-the-shelf, R&D, and OEM customers. This is combined with extensive knowledge in the design and build of PPLN-based laser systems for Red-Green-Blue and mid-IR applications. Six of our staff hold PhDs and the management team can claim a level of commercial expertise and technical knowledge which is exceptional for a young spin-out enterprise.

Featuring a comprehensive suite of patents & know-how for the design and manufacture of periodically-poled materials, Covesion is committed at all times to the delivery of high quality functional products, achieved by investment in knowledge and technology.
