產品概覽

  • 適用於頻寬很窄的氣態與固態雷射
  • 適用於頻寬很寬的二極體雷射淨化
  • 具備高穿透與完整的阻隔能力

TECHSPEC®硬質鍍膜雷射淨化濾光片可深入阻隔不需要的波長,因此對指定的波長具有高穿透力。TECHSPEC®硬質鍍膜雷射淨化濾光片專為搭配使用高效能雷射系統而設計,在單一基材上採用耐用的硬質鍍膜,以確保在更長的使用期內取得可靠的效能。若光學濾光片適用的頻寬很窄(3 - 5nm),則非常適用於消除雷射光源發出的自發輻射雜訊;若濾光片適用的頻寬很寬,則其設計目的在於與二極體波長搭配使用,以便在偵測到雷射光源時消除背景雜訊,從而提高系統的訊雜比。TECHSPEC®硬質鍍膜雷射淨化濾光片在數奈米的雷射波長範圍內具備最大的阻隔能力,因此這些雷射光濾光片非常適用於需求最嚴苛的雷射式檢測設備或應用。
