When selecting a reliable infrared dome manufacturer, verify whether the supplier provides clear specifications including material grade standards, drawing revision control, detailed optical parameters, definite coating ranges and complete inspection protocols. Make sure all technical deviations are stated in written form. Always compare quotations based on identical technical requirements rather than only focusing on unit price to avoid inconsistent manufacturing standards. To deliver an accurate and formal quotation, please provide detailed information including technical drawings or dimensioned sketches, working infrared wavelength band, preferred optical material and order quantity. You are also recommended to supplement coating demands, optical quality grade, mounting structure standards and finished product inspection requirements. Any undecided specifications will be confirmed by our optical engineers during technical review. Yes. We support preliminary budget quotations without finalized drawings. You can submit an inquiry with approximate dimensions, specific application scenarios, operating wavelength range and required quantity. All budget estimates will mark detailed assumption conditions. A formal binding quotation will be issued after the final component specification and technical standard are fully confirmed. Material selection is determined by your actual working conditions, including operating infrared wavelength band, visible light penetration requirements, outdoor/underwater harsh environment exposure degree and overall optical system design. The final performance of infrared domes is affected by material grade, wall thickness and coating configuration. Simply selecting material types cannot guarantee qualified finished product performance, and professional matching evaluation is required. Absolutely. To achieve perfect assembly compatibility, please provide the complete dome drawing and housing structural diagrams, including seating surfaces, fixing retention structure, sealing installation position and assembly clearance parameters. Our engineering team will conduct professional manufacturing feasibility review and confirm all fitting and assembly standards before mass production. For customized anti-reflection coating, you need to clarify core parameters such as target working wavelength bands, minimum/maximum transmission and reflection indicators, light incidence angle range and exact coating surfaces. Clearly mark areas that do not require coating, and specify surface cleaning standards and coating durability requirements according to application environments. 8–14 μm long-wave infrared transmission performance is subject to multiple factors including confirmed material grade, dome wall thickness, professional coating process and standardized testing conditions. Customers need to define whether the requirement is average transmission or minimum single-point transmission. Our team will comprehensively evaluate the full-band performance including the 13–14 μm key interval to formulate achievable transmission indicators. No. The scratch-dig standard only detects surface microscopic defects of optical domes. The actual imaging performance of infrared systems is also affected by surface figure accuracy, uniform wall thickness, transmitted wavefront error and the dome’s installation position in the overall optical system. Imaging quality standards and surface defect standards need to be defined and evaluated separately. We provide full-set inspection reports based on your acceptance standards, covering raw material certification, dimensional tolerance test data, surface defect detection reports, spectral transmission test results and finished optical performance reports. We will clearly distinguish test data from finished product sampling inspection and witness sample inspection to ensure data authenticity and traceability. Yes, prototype trial orders are supported. You can specify prototype quantity and test purposes in the inquiry, including assembly fitting test, optical performance test, environmental durability test and full machine assembly verification. We will confirm prototype feasibility, MOQ rules and exclusive sample pricing according to your customized dome design. The outer diameter cannot represent the full technical standard of custom infrared domes. Quotation differences come from material grade classification, curvature accuracy, wall thickness design, dimensional tolerance level, coating type, inspection standard and order quantity. Tooling cost, professional testing fee, customized packaging and international shipping cost will also affect the final quotation. There is no fixed MOQ for customized infrared domes. The minimum order quantity and production cycle depend on material availability, customized structural complexity, coating process difficulty and strict inspection requirements. Please send your drawings, order quantity and expected delivery date, and we will provide an accurate production schedule. The environmental adaptability of infrared domes cannot be judged only by material type or wall thickness. We need to conduct comprehensive evaluation combined with actual working pressure difference, operating temperature range, humidity, seawater corrosion and other harsh exposure conditions, as well as matching installation and sealing structure to confirm pressure resistance and environmental adaptability. After prototype performance and assembly tests are qualified, we will sort out and confirm the final approved product configuration. Update technical drawings, coating specifications and finished product inspection standards, and record all accepted technical deviations. All confirmed controlled documents will be taken as the unified standard for formal mass production and repeat orders. Please send your technical drawings, required working wavelength band and order quantity to our official email: james@felixglass.com. You can also attach your target delivery date and core technical questions.Custom Infrared Dome FAQ
