Optical Glass Domes

Optical laborers select high-quality optical glasses, including N-BK7, Fused
Silica and sapphire. Through manual and precision instrument processing,
optical domes for harsh environments are produced. Optical glass domes are
corrosion resistant and high-pressure resistant. They are often used in
underwater photography and underwater detection, meterological station
measurement and military missiles, as a protective cover to protect
sensitive sensors and detection equipment.
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.
In addition to the commonly used N-BK7 Domes, RZ Optics Co., Ltd. also
produces optical domes made of fused silica and sapphire.
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.
