Customized Optical Colored Glass Germanium IR Window Optical Germanium Window¹

Product DescriptionProduct OverviewGermanium Windows with excellent transmission across 2-14 μm wavelength and can be used in both mid-wave infrared (IR) and long wave IR systems. Germanium is a widely used material for IR windows and lenses in thermal imaging systems.SpecificationMaterial:Germanium, mono.Dimensions:from 2mm to 400mm, customized according to requirementsThickness0.2 to 50mm (subject to dimensions)Dimension/Thickness Tolerance:up to 0.02mmParallelism:up to 3arcminFlatness:up to 1/2L PV@633nmSurface Quality:up to 40-20Clear Aperture:>90% centeredCoatings:AR coating from UV-IRKey Features1. Optical PropertiesInfrared Transparency: Germanium windows are highly transparent in the infrared spectrum, particularly in the mid-wave infrared (MWIR) and long-wave infrared (LWIR) regions. This makes them ideal for infrared imaging and thermal detection applications. High Refractive Index: Germanium has a relatively high refractive index, which can be advantageous in certain optical designs, such as lenses and windows that require specific focusing or collimating properties. 2. Thermal PropertiesHigh Thermal Conductivity: Germanium has a high thermal conductivity, which allows it to dissipate heat effectively. This is beneficial in applications where thermal management is critical, such as in high-power laser systems. Thermal Stability: Germanium windows can withstand high temperatures without significant degradation of their optical properties. This makes them suitable for use in environments with elevated temperatures. 3. Mechanical PropertiesHigh Mechanical Strength: Germanium is relatively strong and can withstand mechanical stress. This durability is important in applications where the windows may be exposed to physical contact or vibrations. Brittleness: While strong, Germanium is also brittle, which means it can crack or shatter under excessive force. Proper handling and mounting are essential to avoid damage. 4. Chemical PropertiesChemical Inertness: Germanium is chemically inert and resistant to many common chemicals, including acids and bases. This makes it suitable for use in environments where exposure to chemicals is a concern. Hygroscopic Nature: Germanium is not hygroscopic, meaning it does not absorb moisture from the air. This helps maintain its optical properties in humid environments. 5. Other FeaturesCustomizability: Germanium windows can be manufactured in various sizes, shapes, and thicknesses to meet specific application requirements. They can also be coated with anti-reflective or protective coatings to enhance their performance. High Purity: High-purity germanium is used to produce these windows, ensuring consistent and reliable optical properties.InspectionsProduction LineCompany ProfileBand-OpticsBand-Optics Technology was founded in 2008, an ISO 9001:2015 certified factory that has been manufacturing the optical components & lens systems for over 15 years. We primarily fabricate the high-precision off-axis parabolics, toroids, aspherics & spherical lens, domes, prisms, filters, and flat windows by using optical grade glasses, fused silica, sapphire, ZnSe, ZnS, Silicon, Ge, CaF2, Zerodur and Aluminum. We serve the OEM industry, defense, aerospace, semiconductor, medical&bio worldwide. We have highly skilled teams that continue to design inovative products as well as creating cost-effective solutions to meet specifications, timelines and budgets. Our advanced manufacturing process and stringent quality control ensure our products are complying with the rigorous standards demanded by our customers.Factory Advantages1.
