Product Details

The glass used to make lenses is the common window glass or the lumps on wine bottles, shaped like a "crown", and the name "crown glass" or "crown plate glass" comes from this. The glass at that time was uneven and had a lot of foam. In addition to crown glass, there is another type of flint glass with a relatively high lead content. Around 1790, the Frenchman Pierre Louis Gunnard discovered that stirring glass paste could produce glass with a uniform texture. In 1884, Ernst Abbe and Otto Schott of Zeiss founded Schott Glaswerke AG in Jena, Germany. Within a few years, they developed dozens of types of optical glass, among which the invention of barium crown glass with a high refractive index was one of the important achievements of Schott Glaswerke AG.
