The main reasons why optical glass has no streaks after grinding include factors such as high purity of raw materials, furnace structure and forming methods.
Firstly, the high purity of raw materials is one of the reasons why optical glass has no streaks after grinding. The raw materials for optical glass are required to have a purity of over 99% and a low impurity content, usually less than a few parts per 100,000. This high-purity raw material can reduce impurities and unevenness generated during the melting process, thereby avoiding streaks after grinding.
Secondly, the structure of the furnace and the forming method also have an impact on the formation of fringes in Optical Colored Filter Glass. The furnaces for Optical Colored Filter Glass usually use ceramics or platinum as refractory materials and are divided into melting tanks, regulating tanks, refining tanks and homogenizing tanks. This structure can effectively prevent the stirring of the glass during the forming process, thereby reducing the formation of streaks . In addition, the forming methods also include pouring, rolling, and breaking the cylinder, etc. These methods can effectively avoid the streaks caused by stirring.

Finally, the controlling factors in the melting process. During the melting process, strictly controlling the process parameters and the weighing of the raw material section to ensure the uniform mixing and melting of the compound can reduce the occurrence of streaks. Once problems arise, analyze, rectify and correct them in a timely manner to prevent them from escalating .
