High transmission across UV to IR2. Low absorption and minimal signal loss Applications:1. Thermal imaging systems2. Fluorescence imaging3. FTIR (Fourier Transform Infrared) analysis Material Options:1. Monocrystalline and Polycrystalline grades2. UV grade material offers no absorption at lower wavelengths Customization:1. Available in crystal orientations: <100>, <110>, <111>2. AR (Anti-Reflective) coatings available for enhanced transmission at specified wavelengthsCaF2 (Calcium Fluoride) Windows – Technical Datasheet (Condensed)1. Optical? Transmission window: 0.15 μm (UV) – 8 μm (FIR)? Bulk absorption: < 0.3 % cm-1 @ 1–5 μm (typ.)? Refractive index: 1.428 @ 0.59 μm, 1.300 @ 5 μm? Scatter & laser-damage threshold: 5 J cm-2 (10 ns, 1064 nm, 10 Hz) 2. Mechanical? Density: 3.18 g cm-3? Knoop hardness: 158 kg mm-2? Young's modulus: 75.8 GPa? Flexural strength: 36 MPa? Thermal expansion: 18.9 × 10-6 K--1 (20–300 °C) 3. Chemical? Insoluble in water (0.0017 g/100 mL, 25 °C)? Resistant to most acids (pH > 3) & non-alkaline solvents? Slightly hygroscopic—store < 40 % RH, desiccated 4. Typical Specifications (standard catalog parts)? Diameter: 5–150 mm? Thickness: 0.5–20 mm? Dimensional tolerance: +0 / –0.1 mm? Surface quality: 40-20 scratch-dig (MIL-PRF-13830)? Flatness: λ/4 @ 632.8 nm (≤ 50 mm ?)? Parallelism: < 3 arc-min? Bevel: 0.2–0.5 mm × 45°? Coating options: BBAR 2–5 μm, 3–5 μm, 8–12 μm; V-coat @ 1064 nm, 2940 nm, etc. 5. Handling & Cleaning? Use powder-free gloves; avoid skin oils.? Rinse in IPA or acetone, blow-dry with N2.? Do not immerse in aqueous bases (NH4OH, NaOH) > pH 9.? For long-term storage, add silica-gel packet, heat-sealed Al-foil bag. 6. Limitations? Not recommended for > 300 °C continuous duty (thermal shock risk).? Avoid rapid ΔT > 50 °C across aperture.? Mechanical shock > 0.7 MPa may initiate cleavage along {111} planes. 7. Key Applications? FTIR & gas-cell spectroscopy? Thermal-imager dewar windows? Excimer & Er:YAG laser delivery? Aerospace & UAV IR sensor pods (weight savings) Need tighter flatness, high-energy AR coating, or custom edge-sealing? Let me know the wavelength range, beam power, and aperture size and I'll recommend the exact grade and coating stack.SpecificationMaterial:Calcium Fluoride (CaF2), UV & IR gradeDimensions:from 2mm to 400mm, customized according to requirementsThickness0.2 to 50mm (subject to dimensions)Dimension/Thickness Tolerance:up to 0.02mmParallelism:up to 3arcsecFlatness:up to 1/10L PV@633nmSurface Quality:up to 10-5Clear Aperture:>90% centeredCoatings:AR coating from UV-IRRelated ProductsInspectionsProduction LineCompany ProfileCertifications
