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： mfXD1]<.
Example: an erythrocyte (O 8 μm) is photographed using ?n!lU r$:y
the Achroplan objective 100x. The TV adapter has the 7t'(`A 6t/
factor 0.5x: LO"_NeuL
; ;<J
x.
M optical = 100 x 0.5 = 50 x @ ru<4`h
`SCy<w3$+[
The active sensor diagonal of the 1/3”-chip CCD-camera c p$.,V
is 5.3 mm. The monitor in the lecture room has a useful \CcmePTN#x
image diagonal of 61 cm (= 610 mm). r)V Lf#3B
:`D'jF^S
M electronic = 610 mm / 5.3 mm = 115 x br b[})}

The overall magnification then is: Z;hyi'rPJ

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm IWQ&6SDW$z
or 46 mm = 4.6 cm : (cb2j(C

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*0f~eu
