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： b,K1EEJ
Example: an erythrocyte (O 8 μm) is photographed using mybDK'EW
the Achroplan objective 100x. The TV adapter has the T]i~GkD\
factor 0.5x: cu""vtK
(d!vm\-PH
M optical = 100 x 0.5 = 50 x X0=R

The active sensor diagonal of the 1/3”-chip CCD-camera *&AK.n_
is 5.3 mm. The monitor in the lecture room has a useful 8 zY )0
image diagonal of 61 cm (= 610 mm). _c #P

M electronic = 610 mm / 5.3 mm = 115 x 89 lPeFQ`

The overall magnification then is: s&tr84u|

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x =+"XV8Fi,

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm YE-kdzff
or 46 mm = 4.6 cm e%f8|3<6

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？ /_56H?w\
