產品系列說明

在惡劣環境中表現卓越
高強度、高硬度
化學穩定性高
亦提供藍寶石及紅寶石半球形透鏡

藍寶石及紅寶石球形透鏡皆由Al₂0₃製成。紅寶石或摻紅寶石的藍寶石顯示紅色，是因為其包含微量的氧化鉻 (紅寶石球形透鏡中的鉻含量通常超過0.5%)。 While their physical and chemical properties are basically the same, their optical properties are somewhat different. Sapphire has superior optical transmission qualities. Ruby Balls are easier to see and therefore easier to handle for physical applications.
