產品系列說明

  • 經優化,於532nm及1064nm時,絕對反射率小於0.25%
  • 500 - 1100nm範圍內具有出色廣波段穿透率
  • 可做為雙合透鏡的低成本替代方案

TECHSPEC® YAG-BBAR鍍膜消色差透鏡包含由兩個光學元件黏合而成的雙合透鏡,適合用來修正正軸球面像差和色像差。這些消色差透鏡具有廣波段抗反射鍍膜,在500 - 1100nm範圍具有優異的穿透率,經優化後在532及1064nm時絕對反射率小於0.25%。TECHSPEC® YAG-BBAR鍍膜消色差透鏡可使光斑最小化,用於建議可用波長範圍內的多色照明,也可用於聚焦Nd :YAG雷射(尤其是具有對準光束的Nd:YAG雷射)。
