Flint class optical glass sources

Flint class optical glass as the capital basic of optical instruments, and its achievement ambit anon affect the imaging superior of the mirror, but the Internet is not a complete Chinese data, even Google is the abounding adaptation of the ad, sigh. Optical bottle as the advance agreeable is disconnected into the acme and flint glass, beneath 3% for the crown, 3% college than for flint glass, and after with the accretion types of about-face to bottle refractive basis ( refractive basis ) and burning accessory ( burning ) partition, acme bottle refractive basis is usually beneath than 1.6, the accessory of burning ( aswell accepted as the Abbe number, after amount is greater, the burning is baby ) is greater than 50, the adverse of flint glass. Flint bottle ( Flint bottle aswell translated as flint glass, abbreviated to F at the end ): in the average of the seventeenth Century, England southeast of Cretaceous sedimentary band in the flint mines are broadly acclimated in the accomplish of advance bottle ( Flint advance agreeable is usually 4%-60% ), appropriately the name. But the advance bottle in the assembly and processing action would could cause abuse to the environment, is now about use titanium dioxide, zirconium oxide and added alternative.

The condensate backdrop of flint class optical glass. Top refractive basis of ecology abundant lanthanum flint optical glass, its weight percentage: SiO2. Is mainly composed of cerium, lanthanum, praseodymium, neodymium and added attenuate apple metal and iron. Mixed attenuate apple metal crumb is simple to blaze into the adamant caster abrasion admixture fabricated of flint with bend and iron, there will be dust off, discharge sparks. It has top loading accommodation of high-energy radiation, top advance bottle and CaO-B2O2 bottle system, the above can anticipate the gamma ray and X irradiation, which can blot apathetic neutrons and thermal neutrons, mainly acclimated in nuclear industry, medical acreage such as careful and chatter window material. In the gamma ray, assertive X ray radiation, arresting transmittance changes less, varieties and brands and achromatic optical glass, acclimated in the accomplish of top activity betterment optical apparatus and chatter window. Optical bottle is transparent, allure and Physics ( the acme of the anatomy and achievement of a top amount of accord ), with specific and authentic optical constants. Acclimated in the accomplish of optical instruments or automated arrangement lens, prism, mirror, window bottle material.
