Product Information A unique glass in the market D 263® LA eco thin glass (LA = low-alpha) is a colorless borosilicate glass. Currently, SCHOTT manufactures what is currently the only low-alpha radiation sheet glass on the market with the help of a special down-draw method that the company developed on its own. The extremely low-alpha radiation of D 263® LA eco thin glass can be attributed to the fact that only the purest raw materials available and select tank materials are used. It is available as sheet glass in thicknesses ranging from 0.1 mm to 1.3 mm. D 263® LA eco thin glass is manufactured using environmentally friendly refining agents instead of arsenic and antimony. Advantages • Low alpha radiation • High luminous transmittance • Coefficient of thermal expansion similar to that of ceramic • Low roughness due to its fire-polished surface • 8" to 12" wafers possible • Tight thickness control • Easy to cut • Manufactured without using the refining agents arsenic and antimony Technical Data Dimensions : square and round sizes that meet customer specifications Thicknesses : 0.1 mm up to 1.3 mm Luminous transmittance τvD65 (d = 1.1 mm) : 91.7 % Coefficient of mean linear thermal expansion α (20 °C; 300 °C) (static measurement) : 7.2 ⋅ 10-6 K-1 Transformation temperature Tg : 557 °C Dielectric constant εr at 1 MHz : 6.7 Refractive index nD : 1.5230 Density ρ (annealed at 40 °C/h) : 2.51 g/cm3 Intensity of α-radiation : < 0.0050 counts (h ⋅ cm2)
