An optical dome is a concentric window with two spheres. It can be understood as an optical window of a curved moon. Optical dome is used for deep-sea submersible, deep-sea equipment monitoring and underwater robot. At the same time, optical dome is widely used in meteorological industry. It can be used as an optical protective cover to protect the total radiation sensor, the sensor for solar total radiation observation, the net radiation sensor, the PTZ camera, and other precision instruments and equipment used in harsh environments.
Our company produces optical ball covers made of optical glass, fused quartz, silicon and other materials, and can produce optical hemispherical ball covers with a maximum diameter of 300mm. For an ideal optical spherical cover, the convex radius is equal to the sum of the thickness and concave radius. The thickness change at different points on the two surfaces is the main index to measure the accuracy of the spherical cover. Sometimes we call it the congruent thickness and concentricity of the optical spherical cover. For the optical ball cover with size less than 100mm, our concentricity can be controlled within 0.02mm.
