Felix Glass Co., Limited manufactures custom single-crystal sapphire spherical domes for EO/IR sensor windows, guidance heads, airborne optical pods, and other demanding optical assemblies. The original product intent is preserved: a drawing-based hardened sapphire dome with UV to mid-IR transmission, high surface hardness, thermal stability, and optional multi-band coatings. Each dome is built around the customer's optical drawing, including outer diameter, wall thickness, radius, surface figure, clear aperture, edge detail, coating stack, and inspection requirements. For quoting, share the target spectrum, mechanical envelope, operating environment, and tolerance table. Sapphire's Mohs 9 hardness helps resist scratching, windborne particles, cleaning wear, and harsh handling better than many softer infrared optical materials. Single-crystal sapphire supports UV, visible, near-IR, and mid-IR design work from about 150 nm to 5.5 um, depending on thickness and coating. The material remains dimensionally stable across cryogenic and high-temperature environments, supporting aerospace and outdoor optical systems. This product is not a fixed-stock dome. Felix Glass reviews each drawing and aligns material grade, forming, CNC shaping, polishing, hardening, and coating to the assembly requirement. The same workflow can support prototype builds, engineering validation, and repeat production. The sapphire substrate and hardening treatment support protective optical cover roles where airflow, particles, rain, dust, or field handling may affect exposed surfaces. The dome is suitable for optical paths that combine visible alignment, near-infrared sensing, or mid-infrared detection within the sapphire transmission band. Sapphire's corrosion resistance helps maintain optical surfaces in outdoor, marine-adjacent, aerospace, and industrial monitoring environments. Inspection can be arranged around customer drawings, including dimensional checks, surface quality, coating appearance, and spectral transmittance as required. For engineers comparing sapphire with ZnS, ZnSe, fused silica, or standard optical glass, the value is the combined balance of hardness, high-temperature tolerance, chemical stability, and optical transmission. Sapphire is especially useful when the dome is both an optical element and the exposed environmental barrier. Felix Glass can also discuss related sapphire parts under Sapphire Optical Components, including matched windows, lenses, and protective covers for the same system platform. Engineers confirm geometry, tolerance, material, coating, and inspection needs before production planning. Blank preparation, CNC shaping, grinding, and polishing are controlled around the dome radius and clear aperture. Surface treatment and coating are selected for transmission, durability, and operating environment. Dimensional, cosmetic, and optical checks are arranged according to the confirmed purchase specification. Protective sapphire dome covers for guidance and tracking optical paths where hardness and transmission both matter. Airborne and high-speed platform sensor covers requiring stable shape, clear aperture control, and durable surfaces. Monitoring, detection, and thermal imaging systems exposed to abrasion, chemicals, temperature change, or pressure variation. Yes. The renovated content keeps the original EO/IR guidance, aerospace pod, satellite sensing, and harsh-environment optical protection direction, while using clearer engineering language. Yes. Diameter, wall thickness, radius, sag height, mounting edge, and clear aperture can be customized after drawing review. Yes. AR coating, DLC hard coating, and multi-band coating stacks can be discussed according to transmission band and durability requirements. Please provide drawings, quantity, wavelength range, coating requirement, operating environment, inspection standard, and any assembly constraints. Felix Glass will review the optical drawing, material choice, coating request, and inspection standard before confirming manufacturability and quotation.
