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： 9

Example: an erythrocyte (O 8 μm) is photographed using uR7\uvibUO
the Achroplan objective 100x. The TV adapter has the Qm X(s
factor 0.5x: :3x |U,wC
6M `N| %
M optical = 100 x 0.5 = 50 x )} H46

The active sensor diagonal of the 1/3”-chip CCD-camera f}c z_"o4
is 5.3 mm. The monitor in the lecture room has a useful d? /?VooU
image diagonal of 61 cm (= 610 mm). 75V?K

M electronic = 610 mm / 5.3 mm = 115 x O0gLu1*1v

The overall magnification then is: p ft6

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm ^c{,QS{

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？ 0} UJP
