Fused silica is an amorphous (glassy) silica. It is a typical glass with a long-range disorder of its atomic structure. Fused silica is generally used as the main raw material for refractory materials, ceramic raw materials and glass raw materials, epoxy resin casting, electronic sealing materials, electric light sources, medical treatment, casting, and other industries. It is also an ideal filler for chemical industries such as paints and coatings.
MEMS and electronics industry: In MEMS and electronics applications, optical glass wafers are used in the packaging of sensitive components because of their superior functionality and reliability, and stability in the face of harsh environments. Because of optical glass wafers have thermal stability and chemical resistance, glass can also be used as a carrier substrate.
Semiconductor: Optical glass wafers are used as carrier substrates in the production of semiconductor wafers, these optical glass wafers are made of finer materials that are easily bent or torn. Glass was chosen because of its superior chemical and thermal stability, and the potential for reuse can reduce the cost of some applications.
Biotechnology: Optical glass wafers can be used as glass substrates for a variety of biotechnology applications. Borosilicate glass is a ideal choice for medical devices with excellent resistance to high temperature and radiation, such as in X-ray equipment. Optical glass wafers are also used to produce microfluidic chips using nanoimprint lithography, in which glass acts as the substrate. Glass provides the clear optical transparency required for many biotechnology applications, making it a common choice for use as an overlay on devices made of silicon.
Integrated circuit (IC) packaging: Optical glass wafers are used in a variety of integrated circuit (IC) packaging applications, providing better performance and cost-effectiveness as substrates.
Optical glasses work by manipulating light to correct vision impairments such as farsightedness and nearsightedness. A plus/convex (+) lens, crafted from high-quality optical glass, corrects farsightedness by bending incoming light rays and moving the focal point forward, allowing the light to properly focus on the retina. On the other hand, a minus/concave (-) lens addresses nearsightedness by shifting the light’s focal point backward, ensuring it correctly focuses on the retina.
Optical glass is meticulously engineered to minimize impurities and maximize light transmission, making it essential for high-precision applications. Glass wafers, another form of optical glass, are used in various advanced technologies, including semiconductors and photonics.
OST Photonics, a leading optical glass manufacturer, specializes in producing these high-quality optical glass products. Their expertise ensures that the optical glasses and glass wafers they produce meet the stringent requirements of industries ranging from medical imaging to telecommunications. By offering advanced optical solutions, OST Photonics significantly enhances the performance and reliability of optical systems worldwide.
Borofloat 33 (BF33) is often chosen by researchers for its durability and resistance to thermal shock. BF33 , which includes silica, has a very low coefficient of thermal expansion. It also has a much higher melting point, over 1500 degrees Fahrenheit, compared to other types of glass. BF33 is frequently used in research lab equipment as well as optical and lighting applications.
The Advantages of BF33 Glass:
Hypoallergenic
Outstanding Thermal Resistance
Exceptional High-Transparency
High Chemical Durability
Excellent Mechanical Strength
Lead Free
Choosing optical glasses requires consideration of the optical, mechanical and thermal properties of the glass and how these factors will affect applications. Factors to consider are: transparency, uniformity, refractive index, dispersion, density, hardness and melting point.
Optical glass wafers and regular glass wafers differ primarily in their purity and light transmission capabilities. Optical glass wafers are meticulously engineered to minimize impurities and defects, allowing it to transmit light effectively even at significant thicknesses, such as 100 meters. In contrast, regular glass contains more impurities and structural inconsistencies, which hinder its ability to transmit light over long distances. This makes optical glass wafers essential for applications requiring precise light control, such as lenses and scientific instruments.
