Description
The Dome lens is primarily used for physical protection, environmental sealing, and providing high light transmittance while minimizing distortion and other optical properties.
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
