Extended Band UV-Vis-NIR AR Coatings
Enhancing Night Vision Performance
When it comes to ensuring optimal performance in night vision technology, the Extended Band Anti-Reflection Coatings from G&H | Artemis are an essential component. Specially designed to maintain low reflectance in the object lens assembly of night vision goggles, these innovative coatings significantly enhance optical clarity and performance across a wide spectral bandwidth, paving the way for clear, unobstructed views in low-light conditions.
Operating over a spectral bandwidth of 520nm to 950nm, our Extended Band Anti-Reflection Coatings offer an exceptional single-surface average reflectance of less than 0.3%. This greatly reduces glare and maximizes the transmission of available light, allowing for superior visual clarity in night vision applications. Furthermore, the single-surface maximum reflectance across the same spectral range is kept below 0.6%, ensuring a consistent, high-quality visual experience.
But the benefits of our Extended Band Anti-Reflection Coatings extend beyond superior visual performance. They also offer versatility. The spectral bandwidth over which the coating operates can be optimised for other spectral regions, such as 420 to 850nm. This makes these coatings a highly adaptable solution for a wide range of optical needs.
Designed to withstand the toughest environments, our Extended Band Anti-Reflection Coatings are suitable for glasses with a refractive index of 1.48 to 1.88. They comply with the exacting environmental conditions set out in MIL-M-13508C para 4.4.6, MIL-C-675A, MIL-C-675A para 4.6.8, and MIL-C-14806A, ensuring durability, resilience, and reliable performance even under extreme conditions.
Discover the difference that G&H | Artemis' Extended Band Anti-Reflection Coatings can make to your night vision technology. With their superior performance, versatility, and robust durability, they offer an exceptional solution to your low-light optical challenges. Enhance your night vision capabilities with our Extended Band Anti-Reflection Coatings and experience clarity like never before.
