Aerospace & Defense 분야 Optics 솔루션

1. SPACE PHOTONICS / 우주 광학

Space-based platforms must deliver uncompromised signal transmission and reliability in supremely harsh environments. Space-qualified optical components, lens assemblies, and subsystems from G&H deliver consistently excellent connectivity and bandwidth for intrasatellite and satellite-to-ground communications.Our expertise in fiber optics and photonic signal processing is also increasingly leveraged to enhance the sensing capabilities for systems monitoring earth and space environmental conditions. G&H is at the forefront of developing lower SWAP-C photonics modules for this emerging market.

2. IMAGING OPTICS / 광학 영상기

Unmanned aerial vehicles (UAVs) and other airborne platforms gather more image data more quickly during ever-longer flight times. G&H’s precision optical components and advanced lens assemblies enable optimal FOV and resolution for short, mid- and longwave infrared imagers, making them critical elements in aerospace and defense platforms used for intelligence, surveillance, and reconnaissance (ISR) missions. Our SWIR lens assembliesare also used in monitoring directed energy weapons performance.
