產品系列說明

出眾的聚光裝置，適用於紅外線偵測器
在8至14μm範圍內的吸收損失最小

紅外線菲涅耳透鏡塑造於0.015”(0.457mm) 厚的白色彈性柔軟塑膠中。此產品的優勢包括：8 - 14μm範圍內的吸收損失最少、整個透鏡超薄且厚度一致、孔徑大、熱膨脹最小。紅外線傳輸菲涅耳透鏡的設計包含許多複雜的考量。菲涅耳透鏡刻有溝槽的一側應面向較長的共軛 (在用於彙聚輻射光時遠離偵測器)。若光滑的一側因某些非光學原因而需要面向較長的共軛，則透鏡的最大孔徑應是f/1.0。在此狀況下，全內反射會導致超過f/1.0之透鏡區域發出的所有輻射光無法到達影像。即使溝槽面向較長的共軛，超過f/1.0的透鏡區域對成像貢獻的光也很少，而超過f/0.5的透鏡區域對成像沒有任何重要貢獻。
