Fused Silica Domes

►Introduction of Fused Silica Dome

Fused silica dome 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.

Fused Silica Domes offer a variety of excellent characteristics, including a wide range of effective transmittance from the ultraviolet spectrum all the way up to the infrared. It also has a high degree of chemical purity and outstanding mechanical properties, along with superior strength and stiffness to enable the material to withstand various corrosive environments.

Fused Silica Dome properties

Fused Silica Domes offer a variety of outstanding properties that make them an ideal choice for applications in various fields. Their wide ultraviolet spectrum transmission range is among their most sought-after qualities. They demonstrate an excellent level of optical clarity as well, providing superior light transmission qualities without any significant decrease in visible transmittance.

Fused Silica Dome are also known for their very high purity levels. With a purity rating of more than 99.99%, these domes offer superior corrosion resistance and durability in demanding environmental conditions. Moreover, the superior structural and physical characteristics of Fused Silica Domes ensure that their performance is consistent even in the most adverse conditions.

Fused Silica Dome also have high mechanical properties that make them suitable for a range of applications. These domes possess high tensile and flexural strength along with excellent temperature stability, which ensure reliable and long-lasting performance. Moreover, the superior hardness and superior wear and abrasion resistance of these domes also reduce maintenance and replacement needs, as well as increase their overall longevity.

The excellent optical properties of Fused Silica Domes also make them suitable for a range of optical systems. Reflective, refractive, and diffractive optics are all supported with excellent optical fidelity. Additionally, the superior thermal shock resistance and the low coefficient of thermal expansion offered by Fused Silica Domes make them a reliable choice for optically dependent systems.

►Features and Advantages of fused silica domes

Fused quartz is a substance made from natural quartz, including silica and crystal, which is fused at high temperatures.

Fused quartz includes both transparent quartz glass and opaque quartz glass. Among them, transparent quartz glass is made of high purity quartz powder or silicon tetrachloride, etc. by high temperature fusion, in which the SiO2 content is more than 99.95%. Opaque quartz glass is made of ordinary quartz powder and quartz sand by high-temperature fusion, in which the SiO2 content is more than 99.80%.

There are two major difficulties in the production of fused silica: first, the melting temperature is high, the viscosity is relatively large, and the air bubbles are difficult to eliminate; second, in order to get good quality fused silica to improve its purity, the total number of impurities needs to be less than one ten thousandth. The fused silica industry is a high energy consumption industry, requiring large amounts of electrical energy, and there are statistics that the energy consumed in the manufacture of fused silica can account for more than 50% of its production costs. Therefore, reducing energy consumption and improving product quality is related to the positive benefits of the company.
