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： HtMlSgx,8>
Example: an erythrocyte (O 8 μm) is photographed using =w8*n2
the Achroplan objective 100x. The TV adapter has the 8`*(lKiL
factor 0.5x: t

?[kO= hs
M optical = 100 x 0.5 = 50 x ; qvZ *

The active sensor diagonal of the 1/3”-chip CCD-camera E3`KO'v%
is 5.3 mm. The monitor in the lecture room has a useful B]jh$@
image diagonal of 61 cm (= 610 mm). ;$nK

"~GudK &
M electronic = 610 mm / 5.3 mm = 115 x n^'{{@&(v

The overall magnification then is: 4}gwMjU-B

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x -WEiY

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm ,TL~];J'

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？ CnAh Ef)b
