the beam from the laser l passes through the shutter s, is spread by the objective lens . 激光器L發(fā)出的光束經(jīng)過(guò)快門S,被物鏡所擴(kuò)散。
Alternatively, we can image that the incoming wave is diffracted by the object and the resulting diffracted wave is then diffracted again by the objective lens . 換一種方式,我們可以這樣想象:入射波被物體反射,所得到的衍射波再一次受到物鏡的衍射。
The second arises from the spherical aberration present in the objective lens 第二個(gè)出現(xiàn)在目標(biāo)透鏡的球面像差表面。
