BK7 & Optical Glass Domes
Used for visible imaging, PTZ surveillance, LiDAR cover optics and protected optical assemblies where dimensional stability and controlled cost are required.
Optical Domes
Felix Glass manufactures custom spherical optical domes for visible, UV and infrared optical systems, including sapphire domes, ZnSe domes, ZnS domes, fused silica domes and BK7 optical glass domes. Projects are reviewed according to wavelength, dome geometry, pressure load, coating band, wavefront requirement and mounting interface. Infrared thermal imaging domes and LWIR optical components are categorized in the Infrared Optics product group. Material choice affects transmission band, mechanical strength, coating compatibility, dome thickness and inspection method. Typical customization ranges shown for reference. Actual specifications depend on material selection and engineering requirements. Felix Glass supports hemispherical, deep spherical, flanged, pressure-resistant, multispectral and coating-integrated dome designs for OEM/ODM optical systems. Selected for abrasion resistance, marine pressure exposure, outdoor sensing and high-temperature industrial environments. Reviewed for MWIR/LWIR thermal imaging, multispectral sensing and infrared optical protection where material transmission is the primary selection factor. Custom edge forms, mounting shoulders, chamfers and sealing surfaces can be processed according to housing and assembly drawings. Coating design is matched to the substrate, wavelength range, dome curvature, incidence angle and operating environment. Every optical dome is manufactured under documented production and inspection procedures, with traceable process records from raw material verification through final optical inspection. Single-band or custom-band AR coating for visible, NIR and selected infrared systems. Broadband transmission support for multispectral sensors and wide-angle optical assemblies. Hard protective coating option for compatible infrared materials exposed to abrasion or outdoor conditions. Applied when project design requires reflective infrared optical surfaces or special thermal-band behavior. Useful for marine cameras, ROV/AUV domes, outdoor sensing covers and exposed surveillance systems.

Optical dome integration should be reviewed as a coupled optical and mechanical problem. Radius, wall thickness, clear aperture, edge geometry, stress condition, refractive index and coating band all influence the final wavefront behavior and assembly reliability. Dome sag, curvature and pressure load are evaluated together before confirming manufacturable wall thickness. Surface figure, transmitted wavefront and clear aperture must match the optical path and sensor tolerance. Flanges, shoulders, chamfers and sealing edges are processed according to housing drawings. Marine pressure, humidity, abrasion, thermal load and cleaning method affect material and coating selection. Custom optical domes are used as protective and transmitting spherical optical elements in systems where flat windows cannot meet field-of-view, pressure or packaging requirements. Felix Glass supports drawing-based review for off-axis, flanged, partial spherical, window-integrated and housing-matched dome geometries. Feasibility is confirmed according to material brittleness, tool access, minimum edge thickness, polishing route and inspection method. Felix Glass owns full-process 5-axis CNC spherical grinding, ultra-precision polishing and vacuum coating production lines, supported by an independent optical laboratory with Zygo interferometers, spectrophotometers and surface profile inspection systems. Optical domes are commonly evaluated together with windows, lenses, prisms, filters and infrared optical components. Infrared thermal imaging domes and LWIR optical components are categorized in the Infrared Optics product group. Manufacturing support is available for medical device projects based on customer quality requirements. Felix Glass also provides long-term OEM/ODM supply for aerospace-related optical systems, LiDAR sensing, thermal imaging, marine vision, medical optics and semiconductor inspection. Size depends on material, radius, wall thickness and inspection requirement. BK7 and fused silica can usually support larger diameters than ZnSe or ZnS, subject to drawing review. Yes. Radius, sag, hemisphere depth and partial spherical geometry can be reviewed according to optical path and mechanical housing requirements. Typical RFQs include outer diameter, inner diameter, wall thickness, radius, clear aperture, edge thickness, surface quality, wavefront and coating band. Sapphire is selected for hardness and harsh exposure, ZnSe and ZnS for infrared transmission, fused silica for UV and thermal stability, and BK7 for visible optical assemblies. Yes, but pressure depth, sealing design, safety factor and dome thickness must be evaluated together with the selected material and housing design. Wavefront testing can be arranged for qualified geometries and materials. The exact method depends on dome diameter, curvature, wavelength and fixture feasibility. Hemispherical domes are commonly used as protective optical covers, while full spherical forms are more specialized and require separate review for polishing and inspection access. ZnSe, ZnS and other infrared materials may be reviewed depending on wavelength, system design and coating requirements. For detailed infrared optical material selection and professional LWIR optical solutions, please refer to our dedicated Infrared Optics product group. Cleaning method depends on coating and material. Use approved optical cleaning procedures and avoid abrasive wiping, especially on softer infrared materials. Available options include AR, BBAR, DLC hard protective coating, infrared reflective coating and hydrophobic or oleophobic anti-fouling coating where compatible. Yes. Marine projects are reviewed for pressure load, sealing edge, coating durability, cleaning exposure and optical field-of-view requirements. Off-axis and special geometry optical domes can be evaluated from drawings or 3D models, including tool access and inspection feasibility. Manufacturing support is available for medical device projects based on customer quality requirements and documented inspection needs. This page covers broad optical dome capability. Dedicated LWIR and infrared material solutions are organized under the Infrared Optics product group to keep search intent clear. Please provide 2D drawings, STEP or IGES files, material, diameter, radius, wall thickness, coating band, wavefront requirement, quantity and application environment. The process normally includes drawing review, material selection, quotation, prototype production, inspection confirmation, coating, final inspection and repeat production planning.
