Optical glass has high transparency, high physical and chemical uniformity, precision and special optical coefficient. Moreover, it has different specific parameters and indexes, so it is convenient for researchers to achieve a certain purpose smoothly when they are manufactured into glasses. And there are many kinds of optical glass, such as colorless optical glass, radiation-proof optical glass, radiation-resistant optical glass, colored optical glass, ultraviolet and infrared optical glass, etc. With ultra-high pressure waterjet under the control of computer, it can not only cut any workpiece, but also have little influence on material texture. Because of its low cost, easy operation and high yield, waterjet cutting has become the mainstream processing equipment for optical glass processing.
