Sapphire Half Dome Cover Lens

Optical domes can be made from various materials, including zinc selenide, zinc sulfide, or germanium for visible and infrared light. For applications that only require the transmission of visible light, such as camera sensors or meteorological applications, BK7 or fused silica is a good choice. BK7 has good chemical durability and offers excellent transmission from 300 nm to 2 μm. For the ultraviolet range, UV-grade fused silica can be used. These fused silica domes can withstand high pressure and are particularly suitable for underwater applications.

Sapphire dome lenses are high-quality optical components used for camera protection, typically in imaging devices subjected to harsh environments. These dome lenses are made of sapphire, known for its rugged nature, making them suitable for severe conditions. The main features of sapphire dome lenses include high transparency, strength, and resistance to thermal shock. They find wide applications in aerospace, defense, and optical fields. Custom-machined sapphire domes can be produced with diameters up to 400mm, surface quality of 40/20, surface roughness of Rz 0.05, and surface form error of 1.0 fringe over any 25mm diameter zone
