Sapphire Ball Lenses
Compact spherical elements for coupling, sensing and short optical-path assemblies.
Sapphire Optical Lenses
Felix Glass Co., Limited supports drawing-based sapphire optical lenses for fiber coupling, sensing, imaging, laser-adjacent, aerospace-related and precision instrument projects. Lens geometry, crystal orientation, polishing, edge treatment and coating are reviewed around the actual optical and mechanical requirements. A sapphire optical lens is a shaped and polished single-crystal aluminum oxide component that combines optical transmission with high surface hardness, thermal stability and chemical resistance. It is considered when common optical glass may face abrasion, heat, pressure, corrosive exposure or repeated handling. The appropriate form depends on beam behavior, working distance, assembly space and the way the lens is mounted. Felix Glass Co., Limited can review standard concepts and non-standard geometries before production. Reduced-profile options where a flat mounting face helps simplify integration. One flat and one curved surface for focusing or collimating in custom instruments. Drawing-based diameters, radii, thicknesses, chamfers, flats and mounting features. A useful request identifies both the optical function and the installation environment. This allows curvature, thickness, surface quality and coating decisions to be evaluated together rather than as isolated line items. Sapphire is selected when an optical element must remain functional in a mechanically or thermally demanding location. Final suitability depends on the complete system design and validation plan. Ball and half ball forms can support compact coupling layouts when geometry is matched to the source and fiber. Durable lens surfaces can suit sensors exposed to particles, cleaning cycles or frequent contact. Sapphire may be evaluated for optical paths near heat, process equipment or temperature cycling. Low-profile and custom shapes can be reviewed for weight, mounting and environmental constraints.

Custom sapphire half ball lens for fiber coupling, with optical polishing, optional AR coating, and 2–50 mm diameters.
A complete drawing reduces interpretation risk and gives the engineering team a consistent basis for feasibility review, inspection and packaging. Each project moves through a defined review path so optical, mechanical and quality requirements stay aligned. Confirm drawing revision, use environment, quantity and critical features. Review sapphire blank, orientation and allowance for the selected geometry. Apply machining and grinding steps suited to curvature and dimensional control. Develop optical surfaces and edge conditions around the stated specification. Check agreed dimensions and optical characteristics using the project plan. Use separated, clean packaging appropriate for polished optical parts. Coating is not automatically required. The decision should account for wavelength, angle of incidence, environmental exposure, cleaning method and allowable reflection. Where coating is selected, the coated region and witness-sample expectations should be stated on the drawing or purchase specification. The inspection plan should reflect the features that matter to the final assembly. Not every project requires the same measurement depth, so critical characteristics are agreed before manufacturing. The project conversation is centered on manufacturability, documented requirements and repeatable supply. This is useful for engineering teams that need custom sapphire lens geometry rather than a generic catalog substitute. Critical dimensions and acceptance points can be clarified before quotation. Geometry, polishing, edge treatment and optional coating are reviewed together. Measurement expectations can be aligned with the function of the finished lens. Initial samples can provide feedback before a repeat order or production batch. Yes. Diameter, flat location, edge treatment and related tolerances can be reviewed from a drawing or optical requirement. Provide diameter, center thickness, radius or focal requirement, surface quality, clear aperture, wavelength and coating needs. No single material is suitable for every system. The working band, source, detector and transmission target should be reviewed before material selection. Coating options can be evaluated for the required wavelength, incidence angle and service environment. Feasibility depends on the full specification. Identify critical dimensions, tolerances, datums, surface quality, coating area, edge condition, quantity and any special inspection requirement. Prototype or sample planning can be discussed based on geometry, material availability, tooling needs and inspection scope. Share the drawing, optical function, working wavelength, service environment and expected quantity. Felix Glass Co., Limited can review the request and identify the information needed for quotation.
