Product Introductions
Borosilicate glass has a very good homogeneity and very high transparency in the UV/visible/near IR range. The glass has low thermal expansion and high thermal resistance that make it particularly suitable for areas of application where high temperatures and thermal gradients are involved.
Thermal Properties
Borosilicate glass has one of the lowest coefficients of thermal expansion for conventional glass materials,which provides it with good thermal shock resistance.With a maximum long term use temperature of 450°C, borosilicate glass is a good choice for applications requiring good thermal stability.

Application
Borosilicate glass has a wide variety of uses ranging from cookware to lab equipment as well as a component of high quality products such as implantable medical devices and devices used in space exploration
Lighting
Many high-quality flashlights use borosilicate glass for the lens. This allows for a higher percentage of light transmittance through the lens compared to plastics and lower-quality glass.
Several types of high-intensity discharge (HID) lamps, such as mercury vapor and metal halide lamps, use borosilicate glass as the outer envelope material.
New lampworking techniques led to artistic applications such as contemporary glass marbles. Borosilicate is commonly used in the glassblowing form of lampworking and the artists create a range of products ranging from jewelry, kitchenware, to sculpture as well as for artistic glass tobacco pipes.
Lighting manufacturers use borosilicate glass in their refractors.
Organic light emitting diode (for display and lighting purposes) also uses borosilicate glass (BK7). The thicknesses of the BK7 glass substrates are usually less than 1 millimeter for the OLED fabrication. Due to its optical and mechanical characteristics in relation with cost, BK7 is a common substrate in OLEDs. However, depending on the application, sodalime glass substrates of similar thicknesses are also used in OLED fabrication.
Optics
Most astronomical reflecting telescope glass mirror components are made of borosilicate glass because of its low coefficient of expansion with heat. This makes very precise optical surfaces possible that change very little with temperature, and matched glass mirror components that "track" across temperature changes and retain the optical system's characteristics.
