About Company
G&H was founded G&H in Ilminster, Somerset in 1948. The core skills at the time were centered on manufacturing scientific optical components and crystalline materials. These skills are still very much at the cornerstone of the current operations at Ilminster with global sales of acousto-optics, crystal optics and precision optics. The company now works as a supply chain partner in aerospace & defence, industrial, life science and scientific research sectors providing systems and components based on a broad range of photonic technologies.
From its origins as a craft-based optical engineering company rich in practical optical manufacturing skills, G&H has undergone a transformation over the last twenty years into a high-technology photonics business through an acquisition policy of the best-in-breed companies in individual technology areas . The company now has manufacturing sites in the US in California, New Hampshire, Maryland, Massachusetts, Ohio, and Virginia, in addition to its three UK facilities located in Ashford, Ilminster, Glenrothes, St Asaph, and Torquay, and Shanghai, China.
In 1997 G&H was admitted to the alternative investment market (AIM) on the London Stock Exchange. Today the company comprises eight manufacturing sites, with sales offices in France, Germany, Hong Kong, Japan and Singapore with additional representation by a global network of distributors.
We have three core business:
AEROSPACE AND DEFENCE, INDUSTRIAL & TELECOM, LIFE SCIENCES, AND BIOPHOTONICS with our expertise centering on the four technologies:
ACOUSTO-OPTICS - Vertically integrated acousto-optics (AO) manufacturing begins with the growth of lithium niobate (LiNbO3) and tellurium dioxide (TeO2) crystals used in AO devices. We orientate, cut, shape and polish crystals before they can be coated. Transducers are wire bonded and devices are packaged. We design drivers suitable for each product range.
ELECTRO-OPTICS - Our electro-optics (EO) manufacturing is also integrated. We grow our own crystal: Beta barium borate (BBO), Cadmium sulfide (CdS), Cadmium selenide (CdSe), Potassium dihydrogen phosphate (KDP), Potassium dideuterium phosphate (KD*P) and Tellurium dioxide (TeO2). Each material has different optical properties and we design and manufacture EO Pockel cells for a range of applications based on these. We also design and manufacture drivers to control and optimize Pockel cell performance for advanced laser systems.
FIBER OPTICS - We are renowned for our active and passive components and photonic modules. We are able to provide high performance space- and Telcordia-qualified products for use in all-fiber systems. Our expertise encompasses challenging areas such as manufacturing HI-REL fused components for under-sea and space deployment, working with challenging materials such as PCF or chalcogenide, and designing and testing low SWaP modules for use in rugged environments.
PRECISION OPTICS - We design and manufacture precision optics components and assemblies that few other companies can. Our planar, aspheric, prism and waveplate products are globally acclaimed. G&H precision PO capabilities cover a wide range of specialized manufacturing techniques from crystal growth, polishing including superpolishing, single point diamond turning, magneto optical finishing (MTF), segmented waveplates, anti-reflection, high reflection, and high laser damage threshold (HLDT) coatings, and adhesive free bonding. Furthermore aerospace and defense prime contractors rely on G&H to design and manufacture complex opto-mechanical assemblies.
