Compared to the germanium, a common material used in infrared field, chalcogenide glasses possess the characteristics of low-cost and the little value of dn/dt. Besides, it is amorphous glass, which is produced the spherical and aspheric lens by using a molding process instead of single-point-diamond turning. Thus the mass manufacture cost of infrared lens will drop obviously, the stability and consistency of product is guaranteed.

相对于红外领域常用的材料单晶锗，硫系玻璃不但具有低成本，折射率随温度变化小的特点，而且，由于它是非晶态材料，可以用精密的模压工艺来代替用于晶体材料的单点金刚石车削工艺，其批量加工的成本得到了大幅的降低，产品的稳定性，一致性也得到了明显的提高。
