Warfighters face a constant trade-off of how much weight they need to carry versus the capabilities they need in the field. In this video, Sgt. 1st Class Jacob Braun breaks down every gear a US Army Ranger carries in their aviator kit bag during a night-raid mission.
The bag includes protective gear, ammunition, and a Samsung Galaxy phone. Sgt. Braun explains why each item is integral to a Ranger's mission. According to the Army, Rangers are the branch's "premier special operations light infantry raid force.” He comments that this kit bag typically weighs about 75 pounds. One of the essential items in his bag is the PVS-31 night vision goggles (timestamp 1:23). Because it hangs off the front of his ballistic helmet, the goggles’ weight is of specific concern. Every gram of weight savings improves mobility, reduces neck strain, and improves the center of gravity for warfighters like Sgt.Braun. Hybrid LGRIN (Layered Gradient Refractive Index) optics are one of the new technologies aimed at making field bag kits more effective, weighing less, and delivering more capabilities.
Hybrid optics leverage the strengths of glass and polymer materials, resulting in a synergistic solution that outperforms traditional optics in several key areas. LGRIN is a revolutionary new metamaterial that leaps forward in optics capability and AI-driven design. Hybrid LGRIN optics lenses are up to 2x thinner and 50% lighter than glass lenses and offer unmatched performance in field of view, color clarity, and distance. They enable optics designers to reduce the size and weight of optics systems with increased performance capabilities that include:
In the ever-evolving world of military technology, the demand for lightweight, high-performance night vision and fire control systems has never been greater. While offering exceptional image quality, traditional glass optics often come at the cost of increased weight and bulk, hindering mobility and agility in the field. Enter hybrid optics – a revolutionary approach that combines the best of both worlds by integrating glass and polymer optics into a single system.
Night Vision Systems: Hybrid optics are particularly beneficial for advanced night vision systems used by ground troops and in various military platforms like aircraft and satellites. The weight reduction from incorporating polymer optics makes the night vision systems more portable and maneuverable for soldiers. Polymer optics' increased durability makes the systems more resilient to harsh environments and abrasive conditions.
Fire Control and Targeting Systems: Hybrid optics can benefit fire control systems requiring precise targeting and weapon guidance. Polymer optics' thermal management capabilities help maintain consistent image quality across varying temperatures. The cost efficiency of polymer manufacturing also makes hybrid optics an attractive option for these critical systems.
Enhanced Situational Awareness Systems: The Hybrid Augmented Reality Sighting System (HARSS) combines hybrid optics with augmented reality technology. Such systems can improve soldiers' situational awareness and decision-making capabilities by overlaying critical information in their field of view during operations.
Weight-Sensitive Platforms: For weight-sensitive military platforms like uncrewed aerial vehicles (UAVs) and soldier-worn systems, the significant weight reduction offered by hybrid optics can be a major advantage, improving mobility and endurance without compromising optical performance.
As the demand for advanced night vision and fire control systems continues to grow, the development of hybrid optics is poised to accelerate. Ongoing research and innovation in materials science, optical design, and manufacturing processes will further unlock the potential of this technology, enabling even lighter, more durable, and higher-performing systems.
One area of particular interest is the integration of advanced coatings and surface treatments onto polymer optics. These coatings can enhance optical performance, improve environmental resistance, and extend the operational lifespan of hybrid systems. Additionally, developing new polymer materials with enhanced optical properties and thermal stability will further expand the capabilities of hybrid optics.
Integrating hybrid optics with emerging technologies such as augmented reality, artificial intelligence, and advanced sensor fusion will open up new frontiers in situational awareness, target acquisition, and decision support. Combining the advantages of hybrid optics with these cutting-edge technologies will give military forces a decisive edge in various operational scenarios, from urban warfare to special operations.
Hybrid optics represent a game-changing innovation in night vision and fire control systems. By combining the strengths of glass and polymer materials, these systems offer a unique blend of lightweight design, enhanced durability, improved thermal management, and cost efficiency. As the demand for advanced military technology grows, hybrid optics will play a pivotal role in equipping soldiers and military personnel with the tools they need to succeed in the most challenging environments. The future of night vision and fire control systems is undoubtedly hybrid, and the possibilities are limitless.
