How Does an Opitical Dome Work?
Opitical Dome Overview
Why Use Opitical Dome?
Manufacturing Opitical Dome
Opitical Dome from BO- GLASS Optics
An optical dome is a special optical window composed of two parallel curved surfaces. The usual design is hemispherical. It is mainly used to reduce the impact of the optical system on the external environment. Features that protect some optical components from functioning properly. Therefore, in the design stage of the optical dome, our optical designers usually design the optical dome into a circular window with a large curvature. In special cases, coating processing can also be carried out according to customer needs. This minimizes the impact of ambient light on the optical system. The most common applications are underwater cameras and aerospace or satellite cameras.

BO GLASS provides high-precision optical domes and visible optical surfaces to deliver our custom optical solutions. With one of the largest optical engineering teams and an advanced R&D department, we bring the latest understanding to any product regarding optical domes. It mainly produces visible light optical domes, infrared optical domes, and ultraviolet optical domes, with sizes ranging from 6 mm to 300 mm. Materials such as BK7, fused quartz, sapphire are usually the basic choices.
The first thing to do is to choose a professional optical manufacturer. As a high-quality optical equipment supplier, BO GLASS provides high-precision optical domes. In your selection process, you should mainly pay attention to its surface accuracy, whether the two surfaces are parallel, and the strength of the material. These factors can affect the performance of optical domes.
An optical dome is a special optical window composed of two parallel curved surfaces. It is mainly used to reduce the impact of the optical system on the external environment. Features that protect some optical components from functioning properly. At the same time, it can also provide a clear display view and achieve a function similar to a window. Usually used in extreme conditions. It has important applications in underwater photography and aerospace.
The hemispherical design can significantly maintain optical performance while improving mechanical strength due to the use of high-strength materials. Can effectively protect the optical system. And because the materials used have good light transmittance, the optical operation can be effectively observed.
