產品系列說明

擁有獨特創新設計的低成本色差補正非球面
色差補正較標準消色差透鏡更優
具有與加工的非球面類似的球面像差補正
提供規格資料資訊

TECHSPEC®非球面消色差透鏡可彌補色差補正消色差透鏡與球面像差補正非球面之間的效能差異，從而產生符合成本效益的色差補正非球面元件。TECHSPEC®雙透鏡包括黏合在一起的兩個透鏡，這兩個透鏡搭配使用以實現色差補正功能與很小的RMS光斑尺寸。

雙透鏡的背面已塗上模壓聚合物非球面表面。這些模製品可建立穩定的非球面輪廓，消除或減少典型消色差透鏡中出現的波前誤差，同時推進數值孔徑。典型應用包括光纖對焦或平行化、影像中繼、檢測、掃描與高數值孔徑成像。

這些透鏡榮獲 PhAST/Laser Focus World 光學與光學元件單元創新大獎.
