产品介绍

SpotOptics 公司的Lentino 系统是基于夏克-哈特曼(Shack-Hartmann )原理的新一代波前测试系统，是非球面镜和数码相机镜头质量控制的完整解决方案。直径0.5mm到20mm的光学元件都可测试，并且具有手动、自动调像差校功能。Lentino 测试系统被数码相机制造商Pentax公司用于Optio series 数码相机的质量检测。

可满足不同波长范围的检测需要：

390 nm -1100 nm (Vis)
900 nm-1700 nm (NIR)
125 nm-1100 nm (UV)
应用说明：

Elements that can be tested 应用领域	Lenses/透镜 Group of lenses/ 透镜组(镜头) Aspheric lenses/ 非球面透镜 Digital camera lenses/ 数码相机透镜
Diameter range/ 镜片直径	From 0.5 mm to 20 mm
NA range 数值孔径	About 0.65 to 0.02
Environment 使用环境	实验室或生产线
