Optical windows are transparent components used to protect optical systems while allowing the transmission of light. They are typically flat or curved plates made of materials that have high optical clarity and low absorption properties.
The primary purpose of optical windows is to provide a barrier between the external environment and the sensitive optical components inside a system. They serve to protect these components from dust, moisture, and other contaminants that could degrade their performance. At the same time, optical windows allow light to pass through with minimal distortion or loss, ensuring the efficient transmission of optical signals.
Optical windows are made from a variety of materials, each chosen based on the specific requirements of the application. Common materials used for optical windows include glass, such as borosilicate, fused silica, and sapphire, as well as transparent plastics like acrylic and polycarbonate. Each material offers different optical properties, mechanical strength, and temperature resistance.
