远心镜头
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。

远心镜头产品线
Lately there have been great changes in the image sensor market and of which one has been for a ever larger sensor size and smaller pixel size. Consequently, a sensor of the same size but with a greater pixel number could yield a picture with a much higher resolution.
最近在图像传感器市场有比较大的变化，即图像传感器的尺寸会变得更大，但是像素尺寸则变得更小。因此，传感器的大小相同，但是有更大的像素，可以输出更高分辨率的图像。
The advantage of a reduced pixel size could dramatically increase the number of pixels that could fit into a sensor of the same size. However, a reduced pixel size translates into a reduced surface area for light signals. In this case, the ability of a lens to collect as completely as possible the light signals from the sources and therefore give a higher resolution is readily pursued.
减小像素尺寸可以在相同尺寸的传感器上大大的提高像素数量。然后减小像素尺寸将减小光信号转换的表面积。在这种情况下，镜头需要有能力尽可能多的收集光源的信号（更大的光通量），从而可以得到一个更高的分辨率。
On the other hand, when the pixel size remains the same but the total sensor size is increased to include a much greater pixel number for high resolution purposes, a larger sensor size is needed for a larger image circle.
另一方面，当像素大小保持不变，但是图像传感器的尺寸则随着更多像素数量的增加、更高分辨率的提高而变得更大，一个更大的传感器尺寸需要一个更大的图像直径（镜头直径）。
It is a daunting task to reconcile between pixel size and sensor size with respect to lens light throughput optimization, and is often easily said than done. Nevertheless, VST has successfully elevated the industry benchmark by adding many new models to the lineup for high mega-pixel telecentric lenses in a relatively short period of time.
协调像素大小和传感器大小对于优化镜头的透光量来说是一项艰巨的任务，并且经常是说比做更容易。然而，VST成功的提高了行业标准，通过在相对较短的周期内增加许多新的型号，对于高像素远心镜头产品线。
