產品概覽

  • 小於 0.1% 反射率的雷射光鍍膜
  • Nd:YAG 及 Yb:YAG 波長選項
  • 將典型的雷射光系統損耗降低3%(與具有10個穿透光學元件的0.25%指定系統相較)
  • 提高穿透率,減少了背向反射,鬼影和雜散光

TECHSPEC® λ/10 超低反射窗鏡採用抗反射鍍膜,提供設計波長的反射率低於 0.1%。這類窗鏡採用高品質的熔融石英基材,具備 λ/10 表面平整度及 10-5 表面品質,盡可能減少散射。這類窗鏡具備超低反射率及高損傷閾值,適用於整合至雷射系統,消除表面反射。TECHSPEC λ/10 超低反射窗鏡提供 266nm 至 1064nm 的雷射 V-Coat,相容於 Nd:YAG 及 Yb:YAG 雷射光源。提供 12.7mm 至 50.8mm 的大型直徑尺寸。
