產品介紹

SpotOptics 公司的Lentino 系統是基于夏克-哈特曼(Shack-Hartmann )原理的新一代波前測試系統，是非球面鏡和數碼相機鏡頭質量控制的完整解決方案。直徑0.5mm到20mm的光學元件都可測試，并且具有手動、自動調像差校功能。Lentino 測試系統被數碼相機制造商Pentax公司用于Optio series 數碼相機的質量檢測。

可滿足不同波長范圍的檢測需要：

390 nm -1100 nm (Vis)
900 nm-1700 nm (NIR)
125 nm-1100 nm (UV)
應用說明：

Elements that can be tested 應用領域	Lenses/透鏡 Group of lenses/ 透鏡組(鏡頭) Aspheric lenses/ 非球面透鏡 Digital camera lenses/ 數碼相機透鏡
Diameter range/ 鏡片直徑	From 0.5 mm to 20 mm
NA range 數值孔徑	About 0.65 to 0.02
Environment 使用環境	實驗室或生產線
