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： =HjC .h
Example: an erythrocyte (O 8 μm) is photographed using DO6

The active sensor diagonal of the 1/3”-chip CCD-camera TeKU/&fkc
is 5.3 mm. The monitor in the lecture room has a useful E8L\3V4
image diagonal of 61 cm (= 610 mm). {9v Mc

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 9VI(s>
