Visible Domes

Visible Domes use a CNC high-precision machining machine, and under the condition of precise control of the machine tool and the processing environment, the high-precision spherical dome is ground to meet the quality requirements. The spherical surface is polished to an optical mirror using high precision correction polishing technology, so that the parallelism of the convex surface with respect to the concave surface is less than 0.002mm, ensuring that the image and light propagation characteristics are not distorted.

Features of Visible Domes

Features of Visible Domes
  • One-stop customized production: Solar Valley processes a variety of convex and concave structure visible dome, visible dome shape can be circular, D-type, hemisphere, super hemisphere and other structures.

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

  • Lens performance: Glass domes 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. With few bubbles and inclusions, our custom BK7 domes are ideal for high performance visible applications with clear images, complete specifications and aerospace quality.

    Product indicators:
