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： :',Q6j( s
Example: an erythrocyte (O 8 μm) is photographed using [x.Dw U%S
the Achroplan objective 100x. The TV adapter has the %bs~%6)
factor 0.5x: a.5^zq7# !

M optical = 100 x 0.5 = 50 x <&$:$_ah

The active sensor diagonal of the 1/3”-chip CCD-camera C "We>!
is 5.3 mm. The monitor in the lecture room has a useful Q ]u*Oels
image diagonal of 61 cm (= 610 mm). MiX*PqNTM
[H!8m7i;
M electronic = 610 mm / 5.3 mm = 115 x @9wug!,

The overall magnification then is: ] 5=C3Y

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x o|v_+<zD!

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm =n}+p>\ s

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？ y_=}, a
