Description
Custom optical dome ports for underwater cameras, ROVs and marine observation systems. Felix Glass supplies custom fused silica underwater dome ports with an integrated mounting flange. The curved optical surface and stepped flange can be manufactured to your drawing, with dimensions, optical finish and coating requirements tailored to your camera housing and imaging system. From prototype evaluation to repeat production, define the dome geometry and mounting interface together to achieve the optical performance and mechanical fit your project requires. A dome port provides a curved optical interface between the surrounding water and the camera housing. Its performance depends on dome curvature, wall thickness, surface quality and the position of the camera lens relative to the dome. Lens alignment and entrance-pupil position should be considered during system design, particularly for wide-angle imaging. For subsea use, the dome, flange, supporting seat, retaining mechanism and seals must be considered as a complete assembly. A flange helps define the mounting interface, but does not independently establish a pressure rating. Pressure qualification: Please provide your maximum operating depth, pressure-cycle requirements and housing drawing. Suitability for repeated deep-water operation must be confirmed through engineering assessment and an agreed pressure-test programme for the assembled design. Optional anti-reflection coatings can be tailored to the camera's operating wavelength band. Identify the outer water-facing surface and inner air-facing surface when specifying coatings, as their optical interfaces differ. For an exposed outer coating, include immersion duration, cleaning method and durability requirements in the RFQ. Fused silica is an option for UV and visible optical systems, but material transmission alone does not determine underwater imaging range. Water conditions, illumination, working distance and detector response also influence system performance. Send your PDF drawing and STEP model for a manufacturing review. Specify critical optical zones separately from mounting and non-optical surfaces so that inspection requirements match the function of each area. A depth rating cannot be assigned from the material name or outer diameter alone. Provide the complete dome and housing geometry, operating conditions and required service cycles for assessment. Any depth claim must be supported by qualification of the relevant assembly. The 89 mm dimension is a reference configuration. Please confirm the dimension definition, complete drawing and quantity with Felix Glass. Stock availability and lead time are confirmed in the quotation. Custom dimensions can be reviewed against your drawing, including dome curvature, wall thickness, flange diameter and seating geometry. Final manufacturability is confirmed after drawing review. The product described is the optical dome component. Mounts, O-rings, retainers and assembly services are separate requirements and are included only if listed in the quotation. Please send the drawing, material grade, quantity, optical requirements, operating depth, seal and mounting details, coating specification, delivery destination and requested schedule. Share your design with Felix Glass to review the optical dome, flange geometry and manufacturing requirements. Dongguan Felix Glass Co., Ltd.Fused Silica Subsea Dome Port with Mounting Flange
