G&H is a high-tech engineering business based in Ilminster Somerset, UK, with manufacturing plants in the USA and Europe. A global leader in the field of photonics, G&H advanced systems, components and instrumentation are used, often in testing or rugged environments, in applications in the aerospace & defense, Industrial, life Sciences and scientific research sectors.
G&H’s expertise covers research, design, engineering and through manufacturing and after sales service. Across ten sites G&H make photonic assemblies, systems and components based upon the following key enabling technologies:
Acousto-Optics: Q-switches, tunable filters (AOTF), modulators (multi or single channel), deflectors, pulse pickers and cavity dumpers, frequency shifters, mode lockers.
Electro-Optics: from G&H grown crystals: Pockels cells – BBO LightGate, CdTe IRX, KD*P, TX series large aperture and lithium niobate Q-switches.
Fiber Optics: Active and passive – fiber optic components, fiber optic assemblies, fiber coupled AOM, DFB and DBR Lasers, DFB laser drivers, single mode pump lasers, multi-mode pump lasers, high speed, detectors. Manufacturing for rugged environments including high reliability and space.
Precision Optics: Thin film coating, birefringent, non-linear, planar and aspheric optics, assemblies, crystalline optics, infra-red Optics, glass engineering, research grade mirror substrates, ring laser gyroscope optics, sapphire polishing, silicon carbide polishing, solid etalons, super polishing, waveplates, X-ray and synchrotron. Manufacturing opto-mechanical assemblies.
RF Electronics: Q-switch drivers, modulator drivers, AOTF drivers, fiber-coupled AOM drivers, AO device drivers.
Instrumentation: Spectroradiometers, spectral Imaging and synthesis, spectral radiance and luminance standards, spectral irradiance and illuminance standards, reflectance standards, integrating spheres, radiometer / photometers, detector standards, precision constant current sources, imaging photometers, colorimeters / photometers.
