產品系列說明

  • 供應未鍍膜或 BBAR 鍍膜版本,適用於紫外線、可見光及近紅外線
  • 是成像應用的理想選擇
  • 提供5mm 到 200mm尺寸的圓形和方形版本選項
  • 同時供應λ/10 紫外線熔融石英窗鏡

TECHSPEC® λ/4 紫外線熔融石英窗鏡,是以 40-20 的表面品質及 λ/4 穿透波前規格製造,是成像應用的理想選擇。本系列窗鏡採用紫外線熔融石英基材,可在紫外線 (UV)、可見光乃至於近紅外線 (NIR) 之中提供高穿透率。其中提供寬頻抗反射 (BBAR) 鍍膜選項,協助盡量減少反射損耗並提升穿透率。TECHSPEC λ/4 紫外線熔融石英窗鏡可用於光學成像應用及中低功率雷射應用,並可作為保護窗鏡,特別是在需要穿透紫外線光的應用。
