An inorganic material called optical glass by means of refraction, reflection, transmission of light through the way, or by changing the intensity or spectral distribution of light. Its stable optical properties and high optical uniformity. Optical glass has a high degree of transparency, chemical and physical properties (structure and properties), with a high degree of uniformity, with a specific and accurate optical constants. It can be divided into silicate, borate, phosphate, fluoride and sulfur compounds. According to their variety, mainly in refractive index (nD) - Abbe value (VD) to map the location classification. Traditionally nD>1.60, and nD<1.60 vd="">50, all kinds of glass vd>55 constant (k) crown glass and other types of glass set for flint (f) of glass. Crown glass generally convex lens, a concave lens for flint glass.
Optical glass is the basis and important part of the optoelectronic technology industry. Especially since the 90s of the 20th century, with continuous integration of optical and electronic information science and new material science, as optoelectronic materials based on the optical glass in the optical transmission, optical storage and optical display fields of applications is growing by leaps and bounds, become the information society especially is one of the basic conditions for the development of optoelectronic information technology. With the sustained and steady development of the domestic economy, China's optical glass manufacturing industry is developing rapidly.
In fact, the development of optical glass and optical instruments are inseparable. The new reform of the optical system often puts forward new requirements to the optical glass, thus promoting the development of optical glass, also, the success of new varieties of glass also often in turn promote the development of optical instruments.
Haian Huihong photoelectric instrument factory is a professional production, processing a variety of colored optical glass, colorless optical glass, filter, filter, insulating glass, yellow glass, orange glass, green glass, red glass and so on products enterprises. Company product quality, since the sale of the vast number of customers, warmly welcome you come to discuss the purchase.
