Product DescriptionProduct DescriptionElliptical Mirrors are high-precision optical components designed for laser beam shaping in spectroscopy, medical lasers, and industrial cutting systems. Made from UV-grade fused silica or aluminum substrates with enhanced dielectric coatings, they offer >99% reflectivity across 200 nm–12 μm wavelengths and precise elliptical curvature for accurate beam focusing/redirecting.As a china manufacturer, we provide:· Custom elliptical geometries (aspect ratios 1:1.5–1:5) and surface finishes (Ra < 5 nm)· Fast turnaround for both standard (50–200 mm diameters) and custom sizes· Coatings optimized for UV, visible, or IR applications (including gold/silver for high-power lasers)· Rigorous optical testing to ensure <λ/8 flatness and 20-10 scratch-dig complianceProduct OverviewDesign & GeometryElliptical mirrors feature a curved surface defined by an elliptical profile with two focal points (F1, F2). Light emitted from one focus (F1) converges to the second focus (F2) after reflection, enabling precise beam collimation or focusing. The elliptical axis ratio (semi-major to semi-minor axis) ranges from 1:1 to 5:1, customizable for specific beam shaping needs. Materials & CoatingsSubstrates:UV Fused Silica (CTE: 0.55 ppm/°C): Ideal for high-precision environments requiring thermal stability (e.g., aerospace, metrology).BK7 Glass: Cost-effective option with excellent visible-light transmission (400–700 nm), suitable for general industrial applications. Coatings:Metallic: Aluminum (UV-Vis, 200–800 nm, ≥90% reflectivity), silver (Vis-IR, 450–20,000 nm, ≥97% reflectivity), gold (IR, 2–20 μm, ≥98% reflectivity).Dielectric: Multilayer coatings for narrow-band high reflectivity (≥99.5% @ 750–1100 nm), minimizing absorption in laser spectroscopy. Manufacturing StandardsSurface Finish: Polished to <1 nm RMS roughness for minimal scatter.Flatness: λ/10 @ 633 nm (≤63 nm deviation) tested via interferometry.Edge Treatment: Beveled (0.2–0.5 mm) to prevent chipping during mounting.SpecificationProduct:Elliptical MirrorsMaterial:UVFS, AluminumClear Aperture:>90%Diameter Tolerance:+/-0.1mmThickness Tolerance:+/-0.1mmSurface Quality:20-10Flatness (PV): <1/10L@633nmBevel: Break sharp edgesKey FeaturesBeam Focusing EfficiencyAdjustable Optical PropertiesAchieves spot sizes as small as 30 μm (for 50 mm diameter, 1:1 aspect ratio) when focusing collimated beams, critical for micro-machining and confocal microscopy.Focal Length: Customizable from 25 mm to 300 mm to accommodate divergent or collimated input beams.Aperture Size: Available in diameters from 12.7 mm to 100 mm, with thicknesses of 6–10 mm for mechanical stability.Environmental ResilienceLow Wavefront DistortionProtective overcoats (SiO2 for silver, Al2O3 for gold) enhance resistance to humidity (≤95% RH) and temperature fluctuations (-20°C to +80°C).Engineered to maintain wavefront error <λ/20 @ 633 nm, ensuring high-quality beam propagation in interferometric setups.Why Choose UsPrecision EngineeringOur Elliptical Mirrors undergo 3D profilometry and spectrophotometric testing to ensure <0.1% deviation from specified reflectivity curves.Rapid PrototypingIn-house coating facilities (ion-beam sputtering, electron-beam evaporation) enable fast turnaround for custom wavelength requirements (e.g., 355 nm UV optimization).Global ComplianceMeet ISO 9001:2015 quality standards and RoHS/REACH environmental regulations, with material traceability documentation provided for every order.Application SupportDedicated optical engineers assist with system integration, offering beam propagation simulations and thermal stress analysis for complex setups.Production LineCompany HistoryFactory AdvantagesAs a total solution provider on Optics, we can match your different demands as below optical components:
