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： &- My[t
Example: an erythrocyte (O 8 μm) is photographed using s gZlk9x!Q
the Achroplan objective 100x. The TV adapter has the
b`GKGqb J
factor 0.5x: so Lmr's
t Q.H/ ;
M optical = 100 x 0.5 = 50 x ssH[\i

The active sensor diagonal of the 1/3”-chip CCD-camera |WT]s B0Eq
is 5.3 mm. The monitor in the lecture room has a useful m*l cIa
image diagonal of 61 cm (= 610 mm). tu ;Pm4q7
Z;;A#h'%e
M electronic = 610 mm / 5.3 mm = 115 x wT,=C'

The overall magnification then is: 3". #nN

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x y M-k]_

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm iM V=R2t 2

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？ NE Zu?g
