Anti-Reflective Coatings

Anti-Reflective Coatings on Optical Components
Key Capabilities

• Broadband anti-reflective (BBAR)

• Single band AR, ≤ 0.2% typical reflection

• Meets requirements for severe abrasion, salt fog, humidity, and temperature

• Dual band IR: 400-750 nm & 3-5 µm

• Surface quality < 10-5 scratch - dig

• Thickness uniformities of < 2% are achieved on substrates up to 28"

Anti-Reflective coating are used to reduce the reflected light which results in light loss (Normal glass loses approximately 4% of the light per surface), lower contrast, and ghost images. ZYGO provides anti-reflective coatings ranging from simple one layer coatings to complex multi-layer coatings to meet demanding requirements.

Substrate materials include glass, fused silica, sapphire, ZnS & ZnSe, phosphate laser glass, silicon, and Germanium.
