Infrared (IR) Domes

Infrared (IR) Domes use a CNC high precision machines, grinding high precision spherical domes to meet quality requirements under the condition of precise control of the machine tool and processing environment. 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 Infrared (IR) Domes

Features of Infrared (IR) Domes
  • One-stop customized production: Solar Valley processes a variety of convex and concave structure infrared (IR) ball cover, the shape of the ball cover can be circular, D-type, hemisphere, super hemisphere and so on.

  • Material: zinc sulfide, sapphire, single crystal germanium and other infrared materials.

  • Ball cover performance: strong resistance to mechanical shock and thermal shock, high surface hardness, good transmittance in the infrared field, suitable for harsh environment. Can be made very thin, suitable for near, middle and far infrared spectrum use, usually used as a protective cover for electronic sensors or detectors in the external environment, used to separate the environment on both sides of the instrument to isolate the inside and outside of each other, so as to protect the internal devices. Used in laser, infrared optics, detectors and other scientific and technological fields, complete specifications, aerospace quality.

    Product indicators:

    1. Maximum external dimension of infrared (IR) ball cover: OD≤φ300mm
