產品系列說明

設計用於0°入射角
在 400 - 700nm 的每個表面反射率低於 1.75%
也提供VIS 0° 和 VIS-NIR抗反射鍍膜消色差透鏡

消色差膠合透鏡是由兩個光學元件相互粘合而成，經電腦進行優化，可用於修正在軸線上的球面像差和色差。我們的消色差膠合透鏡採用單層MgF₂鍍膜或寬帶多層鍍膜，可用於可見光譜範圍。還提供近紅外缐（NIR）消色差膠合透鏡和邊緣塗黑消色差膠合透鏡。

消色差膠合透鏡遠優於簡單透鏡，更適用於彩色（"白光"）成像。兩個元件會經配對組成消色差膠合透鏡（字面意思是「沒有顏色的鏡片」）、以修正玻璃內固有的顏色分離。消除了有問題的色差後,消色差膠合透鏡成爲最具成本效益的方法,提供良好的多色照明和成像。
