產品概覽

  • 以均質化分佈塑形雷射光束
  • 圓形或方形輸出形狀
  • 專為 532nm 及 1064nm Nd:YAG 雷射所設計
  • 相容於單模或多模光束

HOLO/OR 繞射漫射器也稱為光束均質機,是一種繞射光學元件 (DOE),可將單模或多模雷射光束轉換為均質化分佈的定義形狀。每個漫射器在設計波長都有指定的漫射角度,並結合透鏡控制光斑大小。HOLO/OR 繞射漫射器提供方形或圓形形狀輸出,此外也提供高均質化版本,相較於標準繞射漫射器,其均質化較高且零階較低。HOLO/OR 繞射漫射器適用於各種雷射應用,包括光束均質化、熱點減少、區域處理,以及雷射材料加工應用。

注意:繞射光學元件不應在其設計波長以外範圍使用。繞射光學元件表面若遭油或其他物質弄髒,將會降低效能。操作這類光學元件時,建議一定要配戴手套或指套

愛特蒙特光學針對雷射應用提供一系列的 HOLO/OR 繞射光學元件,其中包括:

  • 繞射漫射器: 用於將輸入雷射光束轉換為均質化分佈的定義形狀
  • 繞射分光鏡: 用於將輸入雷射光束分割為 1D 陣列或 2D 矩陣輸出
  • 繞射光束整型器: 用於將近乎高斯的雷射光束,轉換為具有均勻平頂強度分佈的定義形狀
  • 繞射光束取樣器: 用於穿透輸入雷射光束,同時產生兩個更高階的光束,可用於監控高功率雷射
  • 繞射軸稜鏡: 用於將輸入雷射光束轉換為可對焦至環形的貝索光束
  • 繞射渦旋相位板: 用於將高斯輪廓光束轉換為甜甜圈形的能量環
