Description
Felix Glass Co., Limited supplies custom H-K9L (BK7) optical glass dome covers designed for PTZ speed dome surveillance cameras, traffic monitoring equipment and outdoor vision systems. We deliver polished spherical dome optics with anti-reflection coating to maintain stable image quality under varied outdoor lighting conditions. As an optical dome manufacturer, we provide drawing-led custom fabrication for visible-light surveillance projects. A spherical H-K9L glass dome cover is adopted for PTZ surveillance when flat optical windows cannot support 360° wide-angle monitoring. The curved dome protects internal camera lenses, reduces wind load, and preserves image uniformity during pan-tilt rotation, while AR coating suppresses surface reflection and ghost images. Visible-band AR coating minimizes glare, improves light transmittance and eliminates ghost reflections for clear monitoring footage. Dome diameter, spherical radius, wall thickness, flange edge and coating specifications can be confirmed according to customer engineering drawings before mass production. The standard substrate material is H-K9L (BK7) optical glass, the mainstream cost-effective solution for outdoor PTZ surveillance. Sapphire and fused silica dome can be offered as upgraded options if higher hardness or extended spectrum transmission is required. Working environment determines final dome dimension, coating scheme and inspection standard. Proper curved geometry and optical coating ensure long-term stable monitoring effect for outdoor vision equipment. For urban security, parking lot and campus pan-tilt surveillance cameras with 360° rotating viewing demand. Road side monitoring equipment needs weather-resistant dome cover to protect internal lens from wind, dust and rain. Outdoor industrial monitoring, port and warehouse security vision equipment with continuous all-day working requirements. Check dome diameter, sphere radius, wall thickness, flange shape, optical clear zone and installation structure. Select H-K9L glass blank, calculate machining allowance according to customer required dome geometry. CNC curve grinding followed by precision polishing to achieve required surface quality for surveillance optics. Deposit AR or customized functional coatings under vacuum environment based on target spectrum and usage environment. Full inspection of dimension, surface quality and coating performance; shockproof packaging to avoid scratch during transit. We support small-batch paid prototype sampling and large-scale bulk production of custom H-K9L surveillance glass dome. To receive accurate quotation, please provide engineering drawing, target order quantity, material requirement, coating specification, tolerance, surface quality grade, working environment and acceptance inspection standards. Sample lead time and bulk delivery time depend on dome geometry complexity, coating type and inspection requirements. Simple standard dome models can complete feasibility evaluation quickly; customized complex structural domes can arrange engineering communication to optimize design and control cost. Application is visible light PTZ surveillance; pursuing balanced optical performance and competitive cost under general outdoor weather conditions. The dome faces frequent sand abrasion, repeated cleaning, harsh marine salt spray and requires extreme scratch resistance. The optical system involves ultraviolet transmission or works under high-temperature extreme environment. Yes. We accept drawing-based customization for dome outer diameter, inner radius, wall thickness, flange structure and optical clear zone. Visible light AR coating design can reach ≥94% single-surface transmittance; exact value depends on wavelength band and glass thickness, please provide spectrum requirement for quotation. Yes. H-K9L owns stable chemical property. Matching AR and AF coating can effectively resist rain, dust and daily outdoor climate erosion for surveillance equipment. Please supply engineering drawing, material selection, dimension parameters, coating requirement, order quantity, application environment and inspection acceptance standard. Quotation relies on engineering review. Share your surveillance application scenario, dome drawing, coating specification and order quantity. Felix Glass will evaluate manufacturability, inspection items and provide formal quotation for custom H-K9L PTZ optical glass dome.
