根據客戶需求提供定制多毛細管x射線光學解決方案。
多毛細管準直透鏡器件 將高度發散的 X 光束轉換成低發散的準平行光束。這些透鏡器件主要應用于 X 射線衍射 (XRD) 和波長色散譜 (WDS)。
多毛細管聚焦透鏡器件 從 X 射線源收集 X 射線的大立體角,并將射線聚焦為小至 10 μm 的光斑。獲得的 X 射線通量密度比用常規針孔準直器獲得的高幾個數量級。這些透鏡器件的主要應用是微量 X 射線熒光 (XRF) 分析,廣泛用于薄膜和電鍍分析、貴金屬評估、合金測量和電路板涂層監測。該透鏡器件還可用于在諸如共焦 XRF 分析和超導能量色散 X 射線光譜儀等應用中進行檢測。使用多毛細管聚焦透鏡器件將顯著提高檢測靈敏度,并允許使用低功率 X 射線管實現高性能。微米級空間分辨率使之可應用于電子和貴金屬小特性評估。多毛細管透鏡器件提供 100x-10,000x 的增益,輸出焦點可小至 10 μm。
