Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...
Precision glass moulding is a replicative process that allows the production of high precision optical components from glass without grinding and polishing. The process is also known as ultra-precision glass pressing. It is used to manufacture precision glass lenses for consumer products such as digital cameras, and high-end products like ...
In 1970, the company created optical fiber, a highly pure optical glass, as thin as a strand of human hair, that could transmit light signals over long distances. Prior to that, copper was the ...
Optical manufacturing and testing is the process of manufacturing and testing optical components. It spans a wide range of manufacturing procedures and optical test configurations. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. [1]
The new Jena optical glass also opened up the possibility of increased performance of photographic lenses. The first use of Jena glass in a photographic lens was by Voigtländer, but as the lens was an old design its performance was not greatly improved.
Ries with raw block of optical crystal at Schott Optical. Ries's sculptures are noted for their changing internal optical compositions and technical proficiency. Ries's primary medium is clear lead crystal, a glass with an unusually high refractive index, extreme light transmission in the visual range, and outstanding homogeneity.

To make glass, the glassmaker starts with the batch, melts it together, forms the glass product, and gradually cools it. The batch is dominated by sand, which contains silica. Smaller quantities of other ingredients, such as soda and limestone, are added to the batch. [2] Additional ingredients may be added to color the glass. For example, an ...
