AR-Coated Optical Toughened Glass for Gunsight Applications
Precision. Clarity. Combat-Ready Performance
Optics Engineered for the World’s Most Demanding Environments
In the field, reliability and optical precision are non-negotiable. Our custom Anti-Reflective (AR) Coated Optical Toughened Glass solutions are designed specifically for gunsight, reflex, and red-dot optics used by elite defence and security professionals worldwide.
From rugged field deployment to high-impact environments, Diamond Coatings delivers optical substrates that provide maximum light transmission, durability, and environmental resistance — all tailored to your product design.
Key Performance Features
- Custom AR Coating Design: Optimised for visible and near-IR wavelengths to ensure maximum transmission and minimal reflection under operational conditions.
- High Impact Resistance: Chemically or thermally toughened glass engineered to withstand recoil shock, vibration, and harsh environmental exposure.
- Optical Precision: Substrate flatness and coating uniformity designed to meet exacting gunsight optical alignment and collimation requirements.
- Low Reflectance: Industry-leading multi-layer AR coatings achieve reflection levels <0.5% per surface, improving target visibility and reticle contrast.
- Environmental Durability: Coatings tested for abrasion resistance, humidity, salt fog, and thermal cycling to meet or exceed MIL-STD standards.
- Custom Form Factors: Available to any custom profile, with edge polishing, apertures, and custom cut-out options for seamless gunsight integration.
