An optical dome is a spherical or hemispherical optical element widely used in various optical systems. Typically, optical domes are employed to protect the internal components of optical systems from external environmental factors while allowing light to pass through freely. They have significant applications in aerospace, military, marine exploration, and security monitoring.
The structural feature of optical domes lies in their nearly parallel surfaces, both concave and convex, designed to minimize light refraction and image distortion. Additionally, the hemispherical or super-hemispherical structure requires special attention to edge polishing during the manufacturing process.
