What are the characteristics and applications of the optical dome?

An optical dome is a window with two spherical surfaces and concentric, which can be understood as a bent-moon optical window piece. The ideal optical dome, the convex radius is equal to the sum of thickness and concave radius, the amount of thickness change at different points of the two surfaces is the main indicator of the accuracy of the dome, sometimes we call it the full thickness of the optical dome, concentricity.

The optical dome is an equal-thickness sphere with the inner and outer spherical centers coinciding, installed in the front end of a flying body moving at high speed, and the external shape can meet the requirements of hydrodynamics.
The optical axis of the optical dome and the outer circle (mechanical axis) should be strictly concentric, and the system installed with the optical dome does not affect the Gaussian index and optical resolution of the rear optical objective

Application Range

Optical dome is used for deep sea submersible, deep sea equipment monitoring, underwater robot, meanwhile, optical dome has wide application in meteorological industry.
Optical dome (also called fairing) is commonly used in the aspect of missile guidance, and has been widely used in infrared guidance and various types of airborne optoelectronic platform weaponry, becoming an important part of these equipment technologies.
Due to the continuous expansion of application fields, the varieties and specifications of dome are also increasing and changing
