Collaboration since 1977

In 1977, William John Perrin founded Wilj International Limited; a small Kent-based company specializing in the design and manufacture of gamma counters for radioimmunoassays. Following the success of its own-brand products, Wilj diversified its business to solidify its position as a premier contract medical design and manufacturer within the medical, diagnostic and scientific industries.

In 1995, the founding name of ‘Wilj International’ was changed to ‘Integrated Technologies Limited’ (ITL) shortly after a buyout by Armenian brothers, George and John Kurkjian. Wanting to stay true to their heritage, the Kurkjian brothers decided to incorporate the red, blue and orange of the Armenian national flag into our branding; the same memorable colors used in our logo today.

We have since grown to become one of the world’s leading contract design, engineering, and manufacturing companies, operating globally from headquarters in Kent, UK.

From humble beginnings to global expansion

In 2008, we established Integrated Electronic Systems (IES), the first wholly-owned and centrally controlled subsidiary of ITL. Based in Shanghai, China, IES provides clients with comprehensive contract manufacturing services and regulatory support for NMPA/CFDA submissions.

Established in 2013, ITL Virginia Inc became the second wholly-owned subsidiary of the group and the main point of contact for customers entering the US market. Based in Richmond, Virginia, ITL VA provides customers with aftermarket servicing and support for medical devices across North America.


We are a G&H company

In August 2018, ITL was acquired by Gooch & Housego PLC. G&H is a photonics technology business headquartered in Ilminster Somerset, UK with operations in the USA and Europe. A world leader in optical designing, testing, and manufacturing, they work with OEM customers worldwide, providing optical systems, assemblies, and components for demanding applications.

In 2023, G&H announced the rebranding of ITL as part of its continuous efforts to integrate the medical device company into the organization. ITL became G&H | ITL, with the rebranding being an exciting milestone as G&H | ITL embarked on a new phase of growth and innovation.

As part of the wider G&H Group, we have access to their technology, expertise, and resources, allowing us to provide design and manufacturing for applications including microscopy, medical imaging, and surgical lasers.
