美国LohnStar中红外腔体衰荡镜CRD Mirror，具有99.99%以上的反射率
美国LohnStar的腔衰荡镜（ cavity ring-down mirrors ，CRD mirror）是全介质镜，采用专有工艺制造，确保散射和吸收损耗极低。这些镜子通常具有99.99%以上的反射率。散射和吸收损耗随波长而变化，但可以低至约10ppm。LohnStar的流程确保了绝对最佳的响铃次数。 在20多年的时间里，隆斯塔光学公司开发了一种独特的工艺，使我们能够制造散射和吸收损耗极低的涂层。正是凭借这一工艺和我们丰富的经验，我们能够为超低损耗镜开发定制涂层设计，用于1米至15米的光腔衰荡应用。这些镜最常用的基底材料是硒化锌、硅和熔融石英。选择正确的基底材料和规格与涂层同样重要。 除了定制涂层，LohnStar还有数量有限的库存镜子可供购买。价格因涂层设计和感兴趣的波长而异。
