G&H Featured in Military Systems & Technology: Countering the Invisible

Print

G&H (LON:GHH), a global leader in optics and photonics technology, is proud to be featured in Military Systems & Technology magazine, December edition.

As directed-energy weapons and optical countermeasures evolve, delivering precision, speed, and survivability has never been more critical. This feature highlights G&H’s latest innovations in optical engineering, designed to help armed forces identify, mitigate, and overcome invisible threats across today’s complex operational environments.

Key technologies presented in the article include:

  • Embedded Sensing for Periscopic Optics
    G&H integrates laser-warning functionality into periscopic optics used in harsh battlefield environments. By embedding narrow-band detectors and beam-sampling components directly within the periscope optical train, crews gain continuous 360° threat awareness without needing additional sensors. This compact, mechanically aligned design delivers accurate detection and reduces cognitive load for operators.

  • Field Optics Protection: FROST Filters for Dismounted Systems
    FROST (Field-Ready Optical Suppression Technology) filters provide multi-band spectral blocking to protect soldiers from laser threats at common battlefield wavelengths. These precision filters reduce back-reflection, improve environmental durability, and prevent unintentional laser signature return, preserving visibility while enhancing survivability in dynamic, close-range engagements.
  • Reticle Fabrication Using Micro-Lithography
    The article highlights G&H’s precision micro-lithography processes, which achieve reticle feature tolerances down to 0.002 mm. Produced in ISO-class cleanrooms and patterned on glass or fused-silica substrates, these custom reticles enhance optical and digital targeting. Their exceptional accuracy enables clear operator-to-target linkage, even under degraded visibility conditions.

  • Systems Integration: Sensor Fusion for Situational Awareness
    G&H’s embedded image periscopes combine optical and electronic sensing into a single converged system, providing real-time battlefield awareness with reduced size, weight, and power requirements. These modules support both digital and optical sighting and incorporate AI-enabled vision features, improving detection accuracy and reducing operator workload.
  • Manufacturing Synergy & Mission Readiness
    The article closes by emphasising G&H’s vertically aligned optics manufacturing ecosystem. With capabilities spanning material preparation, subassembly production, coating, and final system integration, G&H ensures high reliability and consistency across defence platforms. This synergy enables rapid, mission-ready solutions that meet evolving MIL-STD shock, abrasion, and thermal requirements.

As highlighted in Military Systems & Technology, G&H is committed to advancing defence technologies that protect personnel, enhance situational awareness, and ensure mission success.
