25mm Dia., 3mm Thick, 400-1100nm HDAR Coated Fused Silica Window

Product Family Description

• HDAR Coating Achieves Severe Abrasion Requirements of MIL-C-675C
• Low Reflectivity Across the VIS-NIR
• Ideal for Use in Harsh Environments
• Uncoated Fused Silica Windows Also Available

High Durability Anti-Reflection (HDAR) Coated Fused Silica Windows feature precision fused silica substrates with rugged HDAR coatings where frequent handling or cleaning are required. Similar to diamond-like carbon (DLC) coatings, the HDAR coatings are designed to withstand temperature cycling from -80 to +160°F, high humidity for 24 hours, salt spray for a continuous period of 24 hours, and salt solubility for an immersion period of 24 hours. These coatings are deposited on fused silica which has excellent mechanical and thermal stability, ensuring high performance even in harsh environments. High Durability Anti-Reflection (AR) Coated Fused Silica Windows are ideal for aerospace, defense, and industrial applications, as well as any optical application requiring durable protective windows.
