Bena Optics' dome windows primarily consist of hemispheres and hyper-hemispheres, featuring two parallel optical surfaces (convex and concave). We maintain a parallel tolerance of <±2μm, ensuring no image or light distortion. Our optical domes, produced through advanced grinding and polishing techniques, offer unique optical properties. Available in visible, UV, and IR variants, Bena Optics' domes are recognized internationally. They are tailored for various applications, including solar radiation, underwater and deep-sea imaging, sky cameras, and defense. Custom designs are also available to meet specific needs.
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.
