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： ^1b/Y8&8A
Example: an erythrocyte (O 8 μm) is photographed using "E6*.EtTN#
the Achroplan objective 100x. The TV adapter has the o~(/Twxam

The active sensor diagonal of the 1/3”-chip CCD-camera S%sD#0l

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？ b":3J)Y6.
