"The microscope has a magnification of 1000x." (这个显微镜具有1000倍的放大倍率。) "The magnification of the telescope allows us to see distant stars clearly." (望远镜的放大倍率使我们能够清晰地看到遥远的星星。) "The magnification of the camera lens brings out small details in the photograph." ...
Magnification of a lens or a mirror shows how magnified the image of an object is. ... ifv is the image distance and u is the object distance. So, It can be also defined as the ratio of the height of the image to the height of the object. Why is magnification vu? Where f is t...

PURPOSE:To extend the variable magnification range of a lens by moving the first and the second lens groups from a position near the telephoto side of the first variable magnification along moving locus different from those for the first variable magnification while interposing the displacement point...
Its important to avoid rubbing the dirt on the surface with the cloth, you want to let the moistened cloth gently pick up the dirt and then use a clean part of the cloth to finish. With proper gentle cleaning a fine acrylic lens can last a lifetime. 2. To Clean the Magnifier ...
