Optical Glass Dome Lens is a hemispherical optical element made from high-quality optical glass such as BK7 or fused silica. It is designed to provide wide-angle optical coverage while maintaining minimal distortion and high transmission efficiency. These dome lenses are widely used in underwater cameras, aerospace sensors, surveillance systems, and laser scanning devices. The curved geometry allows light to enter from multiple angles with minimal refraction errors, making it ideal for panoramic imaging and environmental protection of sensitive optical components. High surface precision ensures consistent optical performance even in harsh environments.
