Detailed
Felix Glass Co., Limited manufactures custom AR coated BK7 optical dome covers designed for PTZ speed dome security cameras, traffic monitoring equipment and outdoor machine vision systems. Our precision polished spherical BK7 optics adopt anti-reflection coating to suppress ghosting and boost light transmission, delivering stable 24/7 surveillance imaging performance. Poor coating uniformity causes inconsistent transmittance across monitoring field of view Limited customization: hard to match special flange size, composite multi-layer coatings Flat optical windows cannot satisfy the 360° pan-tilt viewing requirements of PTZ cameras. The spherical BK7 dome protects internal lens assemblies from wind, rain and dust. Uniform spherical curvature maintains consistent imaging quality during camera rotation. Visible-band AR coating eliminates surface reflection and glare to capture clear surveillance footage under variable outdoor lighting conditions. Premium K9/BK7 optical glass with controlled surface finish, delivering stable optical performance for visible-light security surveillance systems. Visible spectrum anti-reflection coating minimizes surface reflectivity, improves light throughput and eliminates ghost reflections for outdoor monitoring equipment. Dome diameter, spherical radius, wall thickness, flange edge profile and coating specifications are manufactured strictly according to customer engineering drawings before mass production. BK7 / K9 optical glass serves as the baseline material, offering a cost-effective standard solution for commercial outdoor PTZ surveillance. Sapphire and fused silica domes are available as upgraded alternatives when enhanced abrasion resistance or extended spectrum transmission performance is required. Field operating conditions determine final dome geometry, coating scheme and acceptance criteria. Proper spherical profile and optical coating guarantee reliable long-duration surveillance performance for outdoor vision equipment. Suitable for campus, parking lot and urban security pan-tilt cameras requiring full 360° rotating monitoring coverage. Roadside monitoring equipment adopts weather-resistant dome cover to protect internal lenses against wind, dust and rainfall. Port, warehouse and factory outdoor surveillance vision systems requiring continuous round-the-clock operation. Verify dome diameter, sphere radius, wall thickness, flange geometry, optical clear zone and mounting structure. Select BK7 glass blank and calculate machining allowance according to customer specified dome geometry parameters. CNC curve grinding followed by precision surface polishing to meet surveillance optical surface quality requirements. Deposit AR or customized functional coatings inside vacuum chamber based on target wavelength band and service environment. Full inspection for dimension, surface defects and coating performance; shock-resistant packaging prevents scratches during transit. We support small-batch prototype sampling and large-volume bulk manufacturing of custom BK7 surveillance glass dome. To receive an accurate formal quotation, please provide engineering drawing, order quantity, material requirements, coating specification, tolerance standard, surface quality grade, operating environment and inspection acceptance criteria. Sample lead time and bulk delivery cycle depend on dome geometric complexity, coating type and testing requirements. Standard simple dome models support rapid feasibility assessment; complex structural customized domes can arrange engineering communication to optimize design and control overall project cost. Projects adopt visible-light PTZ surveillance; balancing reliable optical performance and competitive cost under standard outdoor climate conditions. The dome faces frequent sand abrasion, repeated cleaning, severe marine salt fog and requires extreme scratch-resistant performance. The optical system requires ultraviolet transmission or continuous operation under high-temperature extreme environments. Yes. We accept drawing customization for outer diameter, spherical radius, wall thickness, flange structure and optical clear zone. Visible AR coating can deliver ≥94% single-side transmittance; exact value depends on wavelength range and glass thickness. Share your spectrum requirement for formal quotation. BK7 features stable chemical properties. Matched AR and AF coating can effectively resist rain, dust and conventional outdoor climate erosion for surveillance equipment. Please provide engineering drawing, material option, dimension parameters, coating requirements, order quantity, application environment and inspection acceptance standard. Yes, we offer prototype sampling service. Sample lead time varies based on dome shape complexity and coating process, contact our engineering team to confirm timeline. Share your surveillance application scenario, dome engineering drawing, coating specifications and target order quantity. Felix Glass will evaluate manufacturability, inspection items and provide formal quotation for custom AR coated BK7 PTZ optical dome cover.
