產品概覽

  • 提供2mm 到 200mm尺寸的圓形和方形版本選項
  • 7 種寬頻抗反射鍍膜選項
  • 業內最齊全標準N-Bk7 窗鏡選項
  • 另有 超薄 N-BK7 窗鏡可供選擇

TECHSPEC® λ/4 N-BK7 精密窗口片非常適用於工業與低功率雷射應用。藉由精密公差設計,可以最大程度減少光束畸變與散射。廣波段鍍膜選項可延伸這些精密窗口片在可見光與近紅外光譜內的有效工作範圍。TECHSPEC® λ/4 N-BK7 精密窗口片 提供2mm 到 200mm尺寸的圓形和方形版本選項。

注意:此產品系列的新增產品可能會指定透射波前畸變 (TWD) 規格,而不是表面平整度。有關這兩種規格之間差異的更多信息,請參閱我們的應用說明“了解光學窗口片”。
