A new lens that is a modification of the Veselago lens is proposed. It consists of a slab of the left-handed material embedded into a regular material. The materials for the new lens should have the same refractive index, unlike that of the Veselago lens in which the materials should in addition have the same impedance. Therefore the new lens should be easier to manufacture. As the Veselago lens, the new lens might be useful for the three dimensional imaging. In contrast to the Veselago lens the new lens has multiple foci, and it may image an object that is located at any large distance from the slab.
一种对韦谢拉戈透镜进行改进的新型透镜被提了出来。它由一块嵌入常规材料中的左手材料平板组成。与韦谢拉戈透镜不同，新型透镜的材料应具有相同的折射率，而韦谢拉戈透镜的材料除了具有相同的折射率外，还应具有相同的阻抗。因此，新型透镜应该更容易制造。和韦谢拉戈透镜一样，新型透镜可能对三维成像有用。与韦谢拉戈透镜不同的是，新型透镜有多个焦点，并且它可以对位于距平板任意远距离处的物体成像。
