Product DescriptionProduct DescriptionSilicon Windows for MWIR ApplicationsTransparent, Lightweight & Cost-Effective SolutionsProduct Overview:Silicon windows are precision-engineered optical components optimized for the Mid-Wave Infrared (MWIR) region (3–5 μm). Offering broad transmission from 1.2–7 μm, these silicon windows combine low cost, low density, and excellent durability, making them ideal for weight-sensitive imaging, and scientific applications.Key Features:Wide Transmission Range: 1.2–7 μm (MWIR-focused)Low Density: ~2.33 g/cm3 (lighter than germanium or zinc selenide)Cost-Effective: Economical alternative to exotic IR materialsDurable: High hardness (Mohs 7) & thermal stabilityAR-Coated Options: Custom broadband anti-reflection coatings available Applications:Defense: UAV gimbals, missile domes, targeting systemsThermal Imaging: MWIR cameras, spectroscopy, FLIR systemsScientific: Laser optics, IR substrates, research instrumentsOptical Coatings: Durable substrate for high-power IR coatings Specs:Diameter: 5–300 mm (custom sizes available)Thickness: 0.5–10 mmSurface Quality: 40-20 scratch-digParallelism: <1 arcminCoating: Uncoated or BBAR (3–5 μm typical) Why Silicon Window?50% lighter than germanium—critical for drones & aerospace.Stable from -50°C to 200°C (no thermal runaway like ZnSe).Scalable—low material cost for high-volume production.SpecificationMaterial:Silicon, mono., Czochralski GrownDimensions:from 2mm to 500mm, customized according to requirementsThickness0.17 to 50mm (subject to dimensions)Dimension/Thickness Tolerance:up to 0.02mmParallelism:up to 3arminFlatness:up to 1L PV@633nmSurface Quality:up to 40-20Clear Aperture:>90% centeredCoatings:AR coating from 3-5umInspectionsProduction LineCompany HistoryFactory AdvantagesSales TeamProduction TeamInspection Team Band-Optics has a professional sales team, which offer our customers end-to-end 24-hour trustworthy pre-sales and after-sales service and solution.We try our best to meet every customers' needs.Band-Optics has many experienced operators and advanced machines, which importantly guarantee high-quality products.
