An optical dome is a lens with two concentric spheres, similar to a curved plane window. So It is important to do better for dome lens concentricity. the dome lens is widely used fo rDetector, optical sensor and so on. Sunday Optics offer H-K9L, JGS1, Sapphire, Optical glass dome lens with AR Coating.
Our company specializes in manufacturing high-precision optical spherical lenses, dome lens, super hemispherical dome lens, and special-shaped dome lens. The surface can be processed according to the customer's requirements, with a tolerance of 10-5. The shape can be customized to 0.2% of the total area as per the customer's request, and the thickness difference can be controlled within 0.01mm

How to use Dome Lens?
Dome are mainly used in optical design to protect internal components, regulate light transmission, and achieve specific functions. Their design needs to take into account both structure, materials, and optical performance. Widely used in fields such as aerospace, industrial inspection, and security monitoring.
Core function of dome lens
1. Protecting internal components: By preventing external interference such as dust and moisture, it extends the service life of optical components.
2. Light transmission: Ensure that light can pass through freely without affecting the imaging quality (with a light transmittance of over 90%).
3. Environmental adaptability: Capable of withstanding extreme conditions such as high temperatures, high pressures, or underwater environments (such as underwater photography protective dome).
4. Multifunctionality: Designed to be in global shape, hemispherical shape or special shape according to requirements, suitable for different devices.
