用于机器视觉皃strong>双远心透镜
?（strong>双远心透镜能够在整个景深范围内提供不变的放大率
?）可选放大率?.051X 0.128X 0.243X 0.528X 1.00X 或 2.00X
?）兼容带可达2/3英寸探头的C型安装相
?）每个透镜都带各自的测量和性能数据一起发
Thorlab已经和Navitar公司合作设计一系列机器视觉应用下的远心透镜。有亅strong>双远心透镜，物空间和像空间的放大率就都不取决于在视场中的距离（景深范围内）或者位置。这个特点非常适合机器视觉应用：在测量面积时，一个远心透镜能不用考虑物距或位置的变化，得到相同的测量结果。关于远心透镜的详细信息以及它们和标准透镜的区别，请见远心透镜教程标签
Thorlabs供应0.128X?.528X两种放大率的远心透镜。每一个透镜都有一个可变光阑改变f/#值。此类透镜设计用于2/3英寸探头，比如科学CCD相机上的探头。其它CCD和CMOS相机中小?/3英寸的探头也能使用此类透镜，但是视场有所减小（其它规格探头的视场值可以在规格标签中找到）。透镜外壳的外边带有C型安装（1.000英寸-32）螺纹，也兼容我们的相机。使用SM1A10螺纹适配器，C型安装能连接上内或外SM1?.000英寸-40）螺纹使之兼容我们的透镜套筒或其他SM1螺纹安装座
每一个透镜都有详细测试报告展，给出准确规格和透镜图表；下表中可获取PDF报告示例。图表展示的典型性能有场曲率、畸变、相对照度和调制转移函数（MTF），详见上面皃em>曲线标签
请注意，由于MVTC23005和MVTC23013的大小和重量，用户必须小心地适当安装并支撑这些透镜、/p>
