Distance from the Lens的意思|示意

This is the distance (usually in mm.) from the lens (or primary mirror) to the point where the telescope is in focus (focal point).

就是从透镜(或者主反射镜)到焦点的距离，通常单位是毫米(mm)。

The position of the image and the amplitude variation in the optical field are associated with the focus and the distance from the object to the front focal plane of the lens system.

象的空间位置和光场振幅的变化与透镜系统的焦距以及物体距焦平面的位置有关。

The working distance is the distance from the front of the lens to the object under inspection.

工作距离是由镜头前到观察目标物的距离。

You get the most light output from this projector when the lamp power is set to high, and the zoom lens is set to maximum wide angle (shortest throw distance for any given image size).

您得到光输出从这台放映机当灯力量被设置对上流， 并且变焦镜头被设置对最大广角（最短的投掷距离为任何指定的图像大小） 。

The distance information from the lens and 3D matrix metering is then used in the computation to determine the amount of flash light to put out.

由镜头和3D测光系统得到的距离信息会用来计算闪光灯的输出功率。

Here is what I imagine you do have, which I will possess, however briefly, from the safe distance of an observer behind a lens.

这就是我猜想你们所拥有的，从镜头后的旁观者这个安全距离上，我要将其占据，虽然只是暂时的。
