Optical glass is specified in our common glass a special kind of glass, they can provide special optical field, for human beings to understand the microscopic world has deep space provides important material premise.

Optical glass has good optical performance, can made in the optical lens to ensure the good light transmittance, this is very important, in the observation of the outer space environment, general lens on the light loss is very large, the air observation will lose a lot of vision, great observation error; on the other hand, in observation of the microscopic world, the good performance of the optical glass can make the thickness of the lens can be improved to produce more compact observation lens, make the equipment more convenient and practical.

It can be said that without the help of optical glass, our progress in science and technology will be more slow.
