Glass cutting machine technology industry base and important component.
Since the 1990 s, especially in the optical and electronic information, new material science unceasing fusion, as a foundation for optoelectronic materials in the optical transmission of the optical glass, optical storage and application in the field of photoelectric display three is growing by leaps and bounds, becoming social informatization, especially one of the basic conditions for the development of optoelectronic information technology.
With the development of domestic economy sustained, stable and fast development of optical glass manufacturing industry in China.
According to the National Bureau of Statistics data show that in 2010, the optical glass manufacturing industry 246 enterprises above designated size, industry, annual sales income is 234.
0. 5 billion yuan, rose 53.
Profit of 15.
3. 7 billion yuan, an increase of 87.
264 asset size.
5 billion yuan, an increase of 77.
Because of the optical glass manufacturing industry is given priority to with domestic sales, the financial crisis is relatively small, the influence of industry still showed a good momentum of growth.
2, profile used in the manufacture of optical instrument or mechanical system of lens, prisms, mirrors, such as window glass materials.
Including colorless optical glass,
Often referred to as the optical glass)
Coloured optical glass, optical glass, glass cutting machine
, resistant to radiation.
Optical glass with high transparency, chemistry and physics,
Structure and performance)
A high degree of uniformity, with a specific and precise optical constants.
It can be divided into silicate, borate and phosphate, fluoride series and sulfur compounds.
Crown glass general convex lens, flint glass as a concave lens.
Commonly crown glass containing alkali borosilicate system heavy crown glass and barium flint glass belongs to non-alkali borosilicate system, the vast majority of flint glass belongs to lead potassium silicate system.
Along with the continuously broaden the application field of optical glass, its breed in the constantly expanding, its composition almost include all the elements in the periodic table.
By refraction, reflection, through the way of transmission light or by absorbing the change of light intensity and spectral distribution of a kind of inorganic glass material.
Has the stable optical properties and high optical homogeneity.
3 classification colorless optical glass, optical glass for optical constants have specific requirements, characteristics, such as high visible area through selective absorption coloring, etc.
The abbe number size divided corona and flint glass, all kinds of and according to the refractive index and divided into several kinds, and according to the size of the refractive index in turn.
How is used as the telescope and microscope, camera lens, prisms, mirrors, etc.
