RZ Optics Co., Ltd. provides custom optical domes that meet applications of customers. Our company produces optical domes made of optical glass, quartz glass, sapphire and silicon. Our company specializes in processing optical domes for deep-sea exploration, underwater exploration and meteorological exploration. Optical domes produced by our company are used as a window for underwater cameras and underwater robots. They are resistant to seawater corrosion and high pressure. They are also used for meteorological pyrgeometers as protective covers.

RZ Optics Co., Ltd. provides optical glass domes with commercial quality and high precision quality, including N-BK7 domes, Fused Silica domes, Sapphire domes and Silicon domes. The diameter of custom optical glass domes can be 15-280mm. The highest accuracy of concentricity can be less than 0.02mm. The highest accuracy of surface quality can be 40-20.

How can you get custom optical domes?

Please send us design drawings or custom parameters, including diameter, optical material and surface quality. Don't forget to add the requirement of quantities and lead time. Of course, the simplest way is direct to contact us for more information.

N-BK7 Domes

N-BK7 has good transmittance (400nm-1550nm) in the visible and near-infrared spectrum. N-BK7 is a common optical material with low cost and high performance. The refractive index is highly consistent. There are fewer bubbles and streaks in N-BK7. N-BK7 domes are used for solar pyrgeometers to protect the detector from rain and snow. Besides, they prevent harsh environments from affecting the sensitivity of the detector.

Fused Silica Domes

Fused silica is often used in the ultraviolet spectrum, between 185-2500nm, with good transmittance. Fused silica has high chemical purity, corrosion resistance and high mechanical properties. It withstands temperature changes. It is not easy to deliquesce. Fused silica domes are used as a protective cover for underwater detectors and underwater robots to protect their optical imaging systems. In addition, high-precision optical domes hardly affect the imaging effect of underwater detection equipment. 

Sapphire Domes

Sapphire is a stable infrared material, anti-corrosion and anti-deliquesce. Under the same thickness, the performance of sapphire is better than optical glass and quartz glass, but the price is slightly more expensive. Sapphire domes are often used as a protective cover for deep-sea optical imaging systems and guided missiles due to its stable chemical properties, strong pressure resistance and better capabilities of transmission.
