Telecentric lens has parallel chief ray with its optical axis and is ideal for co-axial lighting. Telecentric lenses eliminate
perspective errors in your image and do not change magnification when the WD changed. This allows accurate measurement of 3D
objects or even objects that move up and down.
远心镜头拥有与它的光轴平行的主光线,同轴照明是非常理想的。远心镜头可以消除图像中的透视错误(视角错误),并且可以不改变放大倍率当
工作距离改变时。这样就允许精度测量3D对象甚至是上下移动的对象。
