產品系列說明

  • 將高斯光束整型為平頂外形輪廓
  • 均勻強度的方形輸出形狀
  • 專為 532nm Nd:YAG 雷射所設計
  • 相容於單模光束

HOLO/OR 繞射光束整型器為繞射光學元件 (DOE),可將近乎高斯輪廓的雷射光束,在鏡頭焦點轉換為均勻強度分佈的定義 2D 形狀。這類繞射光束整型器提供平頂或穩定平頂兩種類型。平頂光束整型器的轉換區域較大,不過散焦作用優於穩定平頂光束整型器。HOLO/OR 繞射光束整型器適用於各種材料加工應用,包括雷射切割、劃線及燒蝕,以及晶圓檢測及微影等各種照明應用。

請注意: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
