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： {Tjtj@-
Example: an erythrocyte (O 8 μm) is photographed using |\yDgs%EGy
the Achroplan objective 100x. The TV adapter has the +'{:zN5m

M electronic = 610 mm / 5.3 mm = 115 x r&LCoe'\{i

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm Cys/1DkE

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？ P dE)m/
