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： i|! 9o:
Example: an erythrocyte (O 8 μm) is photographed using ;@;ie8H
the Achroplan objective 100x. The TV adapter has the pU)3*9?cIl
factor 0.5x: _xZb;PbFE

The active sensor diagonal of the 1/3”-chip CCD-camera Nv$gKC6 ,G
is 5.3 mm. The monitor in the lecture room has a useful z@S8H6jM)S

M electronic = 610 mm / 5.3 mm = 115 x z_iyuLRdb

The overall magnification then is: ,Z\,IRn

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x KV&_^xSoh|

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm 5~rY=0t

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？ [g
