Soda Lime glass has been the cornerstone of many optical glass products and has become Nanofilm's biggest product. We're able to produce large quantities in a short period of time while offering many different sizes and thicknesses for your needs. With our vendor connections we can also supply many other types of substrates like Quartz, B270, Boro float etc. Lead time may be longer than normal but our team will help you find the materials best suited for your needs. We also have a long time partnership with the SI Howard Glass Company you may use the link below to direct yourself to their site and order direct. Technical information on the substrates themselves is available on their site as well.
Soda-lime glass is prepared by melting the raw materials, such as sodium carbonate (soda), lime, dolomite, silicon dioxide (silica), aluminium oxide (alumina), and small quantities of fining agents (e.g., sodium sulfate, sodium chloride) in a glass furnace at temperatures locally up to 1675 °C. The temperature is only limited by the quality of the furnace superstructure material and by the glass composition. Relatively inexpensive minerals such as trona, sand, and feldspar are usually used instead of pure chemicals.
Borofloat glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 K−1 at 20 °C), making them resistant to thermal shock, more so than any other common glass.
B270 Glass is a type of optical glass used in lenses and other optical components. It has relatively low refractive index (≈1.52) and low dispersion (with Abbe numbers around 60). Crown glass is produced from alkali-lime silicates containing approximately 10% potassium oxide and is one of the earliest low dispersion glasses.
Quartz Glass is manufactured by melting naturally occurring high purity quartz sand at approximately 2000 °C, either electrically fused or flame fused. Fused quartz is normally transparent. The optical and thermal properties of fused quartz are superior to those of other types of glass due to the purity of quartz. Due to these properties, quartz is used in markets such as semiconductor fabrication and laboratory equipment. It has better ultraviolet transmission than other glasses, making it ideal for use in lenses and other optical devices. The purity demanded is a SiO2 content of >99.995%. A number of unique optical, chemical, mechanical, electrical and thermal properties have made quartz glass an indispensable material in the fabrication of high-tech products.
