Domes With Flange

Domes With Flange is machined using a CNC high precision machining machine, which directly grinds a flanged high precision spherical dome to meet the optical quality requirements under the condition of precise control of the machine tool and the machining environment. The spherical surface is polished to an optical mirror using high precision correction polishing technology, so that the parallelism of the convex surface to the concave surface is less than 0.002mm, ensuring that the image and light propagation characteristics are not distorted, and the dome with flange is easier to install.

Features of Domes With Flange

Features of Domes With Flange
  • One-stop customized production:Solar Valley processes a variety of convex and concave structure with flange dome, dome shape can be circular, D-type, hemisphere, super hemisphere and so on structure.

  • Material: Optical glass, fused quartz, infrared materials, applications range from visible to infrared.

  • Lens performance: domes with flanges are widely used in commercial applications where boundaries need to be protected between different environments; The dome acts as a window, providing protection for electronic sensors or detectors without sacrificing the view, is relatively hard material, and has excellent chemical durability. Domes are almost free of bubbles and inclusions, ideal for high performance applications, better sealing performance, suitable for assembly, clear images, complete specifications, and aerospace quality.

    Product indicators:

    1. Dome with flange maximum dimensions: OD≤φ300mm

    2. The dome with flange can reach the following accuracy levels according to customer requirements:

    Precision level: N≤3 △N≤0.5 Common level: N≤10 △N≤5

  • Surface defect grade: 60-40, 40-20, 20-10 according to customer requirements.
