無限

A number which is very large compared to some characteristic number. For example, in optics, an object which is much further away than the focal length of a lens is said to be "at infinity", as the distance of the image from the lens varies very little as the distance increases further.

Examples :

"In photography, if an object is far enough away – practically at infinity – the camera lens doesn't need to adjust much to keep it in focus. "

写真では、物体が十分に遠く離れている場合、事実上無限遠にある場合、カメラレンズはピントを合わせ続けるためにあまり調整する必要はありません。
