作为红外窗口的晶体通常质脆而软,易于潮解,对温度变化敏感,机械强度又差。因此,给光学冷加工带来了很大困难。传统的机械抛光难度大,效率低,质量差,满足不了需要。为了探索新的抛光方法,近几年来我们对氯化钠红外窗口进行了化学抛光试验,并获得了成功。产品经国内几十个科研单位实际试用,效 As the infrared window of the crystal is usually crisp and soft, easy deliquescence, sensitive to temperature changes, mechanical strength and poor. Therefore, to the optical cold processing has brought great difficulties. Traditional mechanical polishing difficult, low efficiency, poor quality, can not meet the need. In order to explore the new polishing method, in recent years, we conducted a chemical polishing test on the sodium chloride infrared window and achieved success.
