随着红外热像仪在民用领域的广泛应用,低成本高性能的产品正得到业界的重视.本文主要介绍了硫系玻璃在红外光学设计领域的应用前景.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(dn/dt)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.

With the extensive application of infrared thermal camera in commercial field,the product of low cost and high performance is attracted the more attention from the infrared field.The present article introduced the potential of chalcogenide glasses in infrared optics.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.
