Optical glass is defined in terms of refractive index, Abbe number, and other optical properties. Usually, it has a very high material purity, contains only minimal amounts of bubbles and inclusions, and often features an excellent refractive index homogeneity. SCHOTT, OHARA, or CORNING mainly produce the materials in this category. These types of glasses allow the manufacturing of precision optics with increased optical requirements. Optical windows, mirror substrates, lenses, or lens blanks base on these materials. Here you find links with properties and specifications of some of our optical-, block-, drawn-, rolled-, bar-, quartz-, and precision-glass materials like SCHOTT N-BK7, optical quartz glass (fused silica), CORNING ULE® low expansion glass, PYREX®, and VYCOR®.
Technical sheet glass offers a much better surface quality, purity, and flatness than ordinary standard flat glass. These glass products meet the high requirements of many industrial optical and optoelectronic applications. They often provide unique properties such as high-temperature resistance, excellent surface quality, or increased flatness. In many cases, they work in optical applications without the need for additional expensive polishing processes. Here, please find the spec-sheets of our high-grade flat glass materials BOROFLOAT® and B 270® crown glass from SCHOTT as well as 1737F, EAGLE2000, and 7059 from CORNING plus our selected float glass.
Special thin glasses, microplates, and display glass materials offer extraordinary properties. They can be, for example, alkali-free, ultra-thin, flexible, or lightweight. These materials are suitable for thin glass optics, the production of displays, or COG processes. Here you can find the specification sheets of our thin-glass, microsheet, and display glasses like D263 T, AF 32® eco, AS 87 eco, MEMpax®, AF45, AF37 from SCHOTT, as well as 1737F, EAGLE2000, 0211 from CORNING, plus information about our selected float glass.
Our specialty sight glass allows visual observation under particular conditions. Such material types do not need optical quality, as this is not a design requirement for such products. However, they feature unique capabilities such as high-temperature or chemical resistance or protection against X-rays (lead glass). More...
