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： 9dw0<qw1%
Example: an erythrocyte (O 8 μm) is photographed using nO:HB.&@
the Achroplan objective 100x. The TV adapter has the QS%,7'EG
factor 0.5x: / (.'*biQ
{V=vn L--
M optical = 100 x 0.5 = 50 x gm}C\q9

The active sensor diagonal of the 1/3”-chip CCD-camera (A|B@a!Y>
is 5.3 mm. The monitor in the lecture room has a useful +E)e1 : 8

M electronic = 610 mm / 5.3 mm = 115 x L:Ed-=|Uw

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？ :Z ]/Q/$
