CRD Mirror 光腔衰蕩反射鏡
LohnStar CRD Mirror 光腔衰蕩反射鏡是采用專有工藝制造的全介質反射鏡，以確保散射和吸收造成的超低損耗。這些反射鏡通常具有99.99%以上的反射率。散射和吸收引起的損耗隨波長的變化而變化，但可能低至~10ppm。
在20多年的時間里，LohnStar Optics開發了一種獨特的工藝，制造出散射和吸收損失極低的涂層。正是通過這一工藝和豐富的經驗，LohnStar?Optics能夠開發用于1μm至14μm光腔衰蕩應用的超低損耗反射鏡的定制涂層設計。用于這些反射鏡的最常見的襯底材料是硒化鋅、硅和熔融二氧化硅。選擇合適的基材材料和規格與涂層同樣重要。
