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. RZ Optics Co., Ltd. produces custom optical glass domes, according to your requirements. We strictly control the parameters of optical glass domes to ensure the precise design of each batch of custom optical glass domes. For more information, please contact us.
