美國LohnStar中紅外腔體衰蕩鏡CRD Mirror，具有99.99%以上的反射率
美國LohnStar的腔衰蕩鏡（ cavity ring-down mirrors ，CRD mirror）是全介質鏡，采用專有工藝制造，確保散射和吸收損耗極低。這些鏡子通常具有99.99%以上的反射率。散射和吸收損耗隨波長而變化，但可以低至約10ppm。LohnStar的流程確保了絕對最佳的響鈴次數。 ? 在20多年的時間里，隆斯塔光學公司開發了一種獨特的工藝，使我們能夠制造散射和吸收損耗極低的涂層。正是憑借這一工藝和我們豐富的經驗，我們能夠為超低損耗鏡開發定制涂層設計，用于1米至15米的光腔衰蕩應用。這些鏡最常用的基底材料是硒化鋅、硅和熔融石英。選擇正確的基底材料和規格與涂層同樣重要。? 除了定制涂層，LohnStar還有數量有限的庫存鏡子可供購買。價格因涂層設計和感興趣的波長而異。
