Alluxa超窄帶通濾光片介紹
圖1.具有OD6阻斷的超窄帶濾波器，用于1064 nm Nd：YAG激光器。憑借業界可達0.1nm的帶寬和高達98%的透過率，Alluxa的薄膜超窄帶帶通濾光片將優化基于激光的系統的性能。
超窄濾光片非常適合用作激光線，激光清除或激光激發濾光片，適用于熒光顯微鏡，流式細胞儀和DNA測序等應用。它們對激光損傷也很有抵抗力，可確保它們長時間保持高水平的性能。
根據系統的波長范圍和要求，Alluxa窄帶干涉濾波器可以定制設計，以滿足以下一個或多個具有挑戰性的規范：
? 峰值傳輸率高達98％
? Up to 98% peak transmission
? 通過設計達截至深度高達OD10
? Up to OD10 blocking by design
? 波長范圍250nm～1800nm可選
? CWL at any wavelength from the UV to the near IR (～250nm to 1800nm)
? CWL中心波長精度可達0.05nm
? CWL tolerances as tight as 0.05nm
? FWHM帶寬可達0.1nm
? FWHM bandwidths as narrow as0.1nm
? 透過波前差(RMS)：極優0.01λper inch @ 632.8nm
? TWE as low as 0.01 wave RMS/inch measured at 632.8nm
精密控制用的Flat-top
圖2.具有陡峭邊緣，深度阻擋和方形光譜形狀的平頂超窄帶通濾光片。Flat-top,超窄的帶通濾波器特別設計，在整個通帶中有極陡的邊緣和高透過率。這個正方形的光譜形狀可以達到0.1 nm的帶寬。Flat-top窄帶濾波器是理想的激光雷達、拉曼光譜和其他需要使用精密激光發射濾波器或激光清理過濾器的理想選擇。
創新的薄膜涂層工藝的質量和一致性
圖3. ULTRA系列濾光片的波長控制，傳輸和截至在幾種不同的涂層運行中具有高度可重復性。Alluxa薄膜光學干涉濾光片和介質鏡均采用我們的SIRRUS™等離子沉積工藝在我們團隊設計和制造的設備上進行硬涂層。這使我們能夠在幾種不同的涂層上可靠，重復地生產相同的高性能光學薄膜，從而在所有系統中實現一致的性能。
