G&H has world class photonic technologies and capabilities. Dedicated to delivering engineering, design and manufacturing solutions to customers across the globe, our core capabilities span five key technologies: acousto-optics, electro-optics, fiber optics, precision optics and optical systems.
From our sites around the world, in the US, UK, and Far East, we combine high levels of innovation with robust new product development to push the performance of photonics and commercialize new products, side by side with our customers.
G&H technology is integral to the reliability and performance of systems which are deployed in the deepest oceans and orbits in space. For more than 70 years, we have supplied critical components and subsystems for demanding applications in industry and telecoms, aerospace and defense and life sciences.
Through innovation, next generation solutions and global connectivity, we are changing the world with photonics.
AEROSPACE AND DEFENCE
Supplying mission-critical technology for laser, sensing, and imaging applications under and at 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.
G&H's Vice President of Life Sciences, Lars Sandström, reviews the use of acousto-optic components in confocal microscopy in the recently published article of the January/February issue of BioPhotonics magazine.
G&H is pleased to announce that we will be attending the SPIE BiOS and Photonics West exhibitions, taking place January 28 to January 29, 2023 and January 31 to February 2, 2023 in San Francisco, CA.
A contract to supply unique periscope technology as part of the UK’s Challenger 3 program to upgrade the British Army’s main battle tanks has been won by G&H.
Design challenges of producing optical amplifiers include the suppression of amplified spontaneous emission (ASE) and stimulated Brillouin scattering (SBS), and the degradation of the kHz sinusoid amplitude modulated tracking tone.
Erasing full-color tattoos is a much more complicated procedure than removing "traditional" black ink tattoos. The Pockels cell, particularly in relation to wavelength, is key for successful removal.
G&H manufactures a comprehensive range of Pockels cells for applications in wavelengths from the UV to the IR. Pockels cells are used in a variety of applications benefitting from rapid/dynamic polarization control, Q-switching, light intensity control, intensity, modulation, dynamic waveplate, and more.
The latest innovation in optical coatings technology is helping to meet the evolving requirements of today’s semiconductor industry. G&H explains how the latest developments in DUV coatings can optimize your laser tool performance at even shorter wavelengths.
Acousto-Optical Tunable Filters (AOTFs) deliver sharper images, pixel-by-pixel wavelength flexibility, and precise control for confocal microscopy. Lars Sandström, vice president, Life Sciences at G&H, explores how the technology is evolving to further enhance the versatility of confocal microscopy in life sciences.
For many OEMs involved in material processing within manufacturing, fiber and fiber-coupled lasers are at the heart of the value they deliver to their end clients across different application areas.
Learn about light across the spectrum, its uses and advantages/disadvantages in the systems, the solutions that depend upon it, and how technology can pick and mix spectral bands to deliver optimal outcomes for specific purposes.
