產品概覽

  • 提供多個範圍
  • 在每個廣泛的光譜範圍內具有平直回應
  • 具有λ/4與λ/2的相位差

與標準波片不同，不論所用光線的波長為何，消色差波片 (相位延遲片) 都能提供恆定的相位偏移。該裝置使用兩種不同的雙折射晶體材料，以實現對波長的獨立性。波長範圍內產生的延遲相對偏移將在所用的兩種材料之間抵消。消色差波片 (相位延遲片) 的平直回應非常適合搭配使用可調式雷射、多個雷射光系統及其他諸多光譜來源。

設計用於 0° 入射角，±3° 的變化將產生少於 1% 的延遲性變化。 23mm 通光孔徑波片則採用膠接構造。所有消色差波片（相位延遲片）均裝在陽極化鋁外殼中，並清晰標示快光軸。
