Applications of Optical Domes

Optical domes are widely used as protective and functional components in advanced optical systems. Depending on the type—such as radomes, hemispherical domes, super-hemispherical domes, constant-thickness domes, perforated domes, and flanged domes—they provide reliable transmission in UV, visible, and infrared wavelengths.

To enhance performance, domes can be coated with AR (anti-reflective) coatings 2-25um, ITO conductive coatings for electromagnetic shielding, AF (anti-fog/anti-fingerprint) coatings , DLC Coatingor, other customized multilayer coatings. These coating options make the domes suitable for demanding optical and electronic applications.

Typical applications include infrared imaging systems, aerospace and defense optics, laser protection, meteorological sensors, ocean exploration, medical devices, and industrial inspection systems. With high precision, uniform thickness, and materials including sapphire, germanium (Ge), zinc selenide (ZnSe), zinc sulfide (ZnS), calcium fluoride (CaF₂), and silicon (Si), our domes ensure excellent durability, optical performance, and resistance to harsh environments.

Customized designs are available to meet specific customer requirements, covering sizes from φ5 mm to φ350 mm, with strict tolerances and wall thicknesses down to 0.5 mm.
