G&H Fremont

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, we work with OEM customers worldwide, providing optical systems, assemblies and components for demanding applications, often for deployment in harsh environments.

We have three core business:

AEROSPACE AND DEFENCE
Supplying mission-critical technology for laser, sensing, and imaging applications under at a sea, on land, in the air, and in space. Our optical systems, components and assemblies are used in a broad range of offensive and defensive applications.

INDUSTRIAL AND TELECOM
From laser pulse control for materials processing, to sensing and undersea communications, we have a reputation for producing photonics components and assemblies of the highest specification and quality.

LIFE SCIENCES AND BIOPHOTONICS
Medical systems and instrumentation OEMs rely on us as a vertically integrated one stop resource for components, systems and assemblies. We provide solutions for medical imaging, surgical systems, critical care and laboratory applications.

OPTICAL MANUFACTURING CAPABILITIES
Our expertise centers 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.
