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： Ws(#T hA
Example: an erythrocyte (O 8 μm) is photographed using d6hso
the Achroplan objective 100x. The TV adapter has the _K"X
factor 0.5x: :X;AmLf`2u
m]NyEMYg
M optical = 100 x 0.5 = 50 x O;*.dR
Gd 5J<K
The active sensor diagonal of the 1/3”-chip CCD-camera (j ;6}@
is 5.3 mm. The monitor in the lecture room has a useful E64d6z^7u
image diagonal of 61 cm (= 610 mm). ~
-hH#5
N2 ^B
M electronic = 610 mm / 5.3 mm = 115 x <e&*Tx<8
h^KLqPBt{
The overall magnification then is: [1*3 kt*h
p4OiCAW;
Moverall = Moptical x Melectronic = 50 x 115 = 5750 x tgbr/eCoU

0F
The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm p KF>_\
or 46 mm = 4.6 cm *r k!`n&
r%/ *,lLO
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？ L4'FL?~I
