Product DescriptionProduct DescriptionD-shaped Mirrors from our precision manufacturing offer reliable optical solutions for beam steering and spatial optimization. Engineered with high-quality substrates and custom coatings, our mirrors feature precise angular tolerances and durable surfaces, ideal for laser systems, spectrometers, and compact optical setups. As a china manufacturer, we provide tailored designs—custom dimensions, coating materials, and surface finishes—to meet unique application requirements, supported by strict quality control and rapid prototyping capabilities.Product OverviewDesign and StructureMaterials and CoatingsCoatingsD-shaped mirrors feature a semicircular curved surface paired with a straight edge, allowing them to efficiently separate or redirect beams in space-constrained environments. The flat edge is engineered with a sharp bevel (typically 0.1 mm) to minimize diffraction effects when beams pass close to the mirror's edge.Substrates: Commonly constructed from UV fused silica or BK7 glass for high thermal stability and optical clarity. Fused silica is preferred for its low coefficient of thermal expansion, ideal for high-precision applications.Metallic Coatings: Aluminum (UV to visible), silver (visible to IR), and gold (IR) offer broadband reflectivity. For example, protected silver coatings achieve >97% reflectance from 450 nm to 20 μm.Dielectric Coatings: Provide near-total reflection (≥99%) over narrow spectral ranges, such as 750–1100 nm, with minimal absorption.Manufacturing PrecisionThese mirrors undergo rigorous fabrication processes, including ultra-precision grinding and ion-beam sputtering for coating deposition. Surface flatness is maintained at λ/10 @ 633 nm (e.g., ≤63 nm deviation), ensuring minimal wavefront distortion.SpecificationProduct:D-shaped MirrorsMaterial:Fused Silica/BK7Clear Aperture:>90%Diameter Tolerance:+/-0.1mmThickness Tolerance:+/-0.1mmSurface Quality:10-5Flatness (PV): <1/10L@633nmBevel: Break sharp edgesKey FeaturesCompact Beam SeparationHigh Reflectivity and Low LossThe D-shape design allows for the separation of tightly aligned beams (≤0.1 mm spacing) by directing one beam while letting the other pass unobstructed. This is critical in applications like interferometry and laser beam combining.Metallic coatings deliver reflectivity up to 99% in specific wavelength ranges (e.g., silver for 450–20,000 nm).Dielectric coatings offer >99% reflectance over narrow bands, making them suitable for applications requiring minimal energy loss, such as spectroscopy.Customizable ParametersRobust DurabilitySize: Available in diameters from 12.7 mm to 50.8 mm, with thicknesses of 6 mm ±0.2 mm.Surface Quality: Scratch-dig ratings as low as 10-5 (10-μm scratches, 5-μm digs) ensure minimal scattering.Coatings are engineered to resist environmental degradation. For example, protected gold coatings withstand oxidation and maintain performance in harsh conditions.InspectionsProduction LineCompany HistoryOptical SolutionsMedical & Bio-technologyLaser TechnologyBand optics has been continuously invested in the development and production of medical optics for many years and has a rich experience in providing cost-effective precision optical solutions to the medical applications, for example:X EndoscopyX Fluorescence imagingX IR temperature sensorsX Intense pulsed light (IPL)X Medical imagingX MicroscopyX Optical coherence tomographyX SpectrometryX Therapeutic lasersX ThermographyBand Optics is a trusted manufacturer for supplying precision optical laser optics used in laser technology, and can offer improved performance, greater reliability and lower cost.
