请问用ccd相机连光学显微镜的最大放大倍数和有效的最大放大倍数？
我在carl zeiss里看到的资料： Ed^uA+ D
Example: an erythrocyte (O 8 μm) is photographed using LZc$:<J<6
the Achroplan objective 100x. The TV adapter has the "rx^M*"
factor 0.5x: _))I.c=v

is 5.3 mm. The monitor in the lecture room has a useful n|x $vgb

{ eEC:[

这里面总放大倍数是5750倍。为什么这里面的计算没有涉及到c-mount呢？ g ?afX1Sg
