Custom Domes

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.
