At Optosource we have a friendly, highly motivated and enthusiastic team dedicated to helping customers to their best ability.

We have access to the best LED technology on the planet through quality suppliers such as Lamina, Toyoda Gosei, Cotco and Bivar Opto. This gives us access to one of the best product portfolios in the optoelectronic industry giving you an extensive choice of 3mm, 5mm SMD or chip on board products.

All our operating procedures are ISO2000 approved. We offer a flexible approach including kitting, the option to hold buffer stock and other bespoke services.

Optosource has been distributing high brightness LEDs for more than ten years. It is part of the Marl Group, which is recognised globally as one of the industry pioneers with more than thirty years of successful supply history to world-class organisations, such as Eastman Kodak, BAE Systems, Bombardier Transportation, EMI Music and London Underground.

The Optosource and Marl combination offer a unique choice, ranging from component supply, sub-assembly, assembled products and custom projects. We believe this offer is unique, not only in the UK, but throughout Europe. No other company can match the breadth and depth of facilities, resources, access to technology and supply chain management, which is available to our customers

We offer a complete "one-stop shop" solution to any electronic requirement.
