Custom Sapphire & CaF2 Optical Windows – Precision Engineered for Demanding Applications
Ultra-high-purity sapphire (Al₂O₃) and calcium fluoride (CaF₂) optical windows with custom dimensions, optimized for laser systems, aerospace sensors, and medical imaging equipment. Exceptional durability: Sapphire boasts 9.0 Mohs hardness (second only to diamond) and CaF₂ offers near-zero thermal expansion, ideal for extreme environments. Broad spectrum transmission: Sapphire covers UV to IR (0.15–5.5 μm), while CaF₂ excels in deep UV applications (0.13–10 μm) with minimal birefringence. Precision-polished surfaces with λ/10 flatness and 5/1 scratch-dig standards ensure distortion-free performance in lithography, spectroscopy, and high-power laser focusing. Available in custom diameters (1–300 mm), thicknesses (0.5–50 mm), and coatings (AR, HR, hydrophobic) for OEM integration. Bulk pricing for industrial buyers: Wholesale rates apply for orders above 100 units, with ISO 9001-certified batch consistency.
