Customizable Optical Domes

Optical Domes

Optical domes are specialized structures that are used in a variety of applications where optical clarity, durability, and resistance to environmental factors are essential. These structures are typically made of transparent materials, such as acrylic or glass, and are shaped like a dome to provide a curved surface for optical applications. The manufacturing process for custom optical domes involves shaping and polishing the material to achieve high levels of optical performance.

Optical domes are ideal for visible and infrared applications and provide a protective window due to their hemispherical shape. They are ideal for extreme environments because of their strong protective properties.
