Control And Research Of Refractive Index Of Lead Containing Optical Glass

Since optical glass which contained lead have vaired fraction index, so it is difficult to control it is stability, therefore there is a gravity loss in the production of glass, especially, it will educe seveire error while designing the imaging of ray rqad . This article mainly states on the basis of experience of glass production and related theories. After I studied the preparation of raw material melting and anneal, improvement has made on the production techniques of optical glass then made the possibility of producing high refraction index glass (n_d>1 .7), and centre value of the refraction rate could be controled within ±10×10^-5 units.
