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：

Example: an erythrocyte (O 8 μm) is photographed using ^-26K|{3
the Achroplan objective 100x. The TV adapter has the KNqs=:i
factor 0.5x: Wh1 '?#

The active sensor diagonal of the 1/3”-chip CCD-camera wU/BRz8 I
is 5.3 mm. The monitor in the lecture room has a useful l&uBEYx
image diagonal of 61 cm (= 610 mm). y!jq!faqt
t? [8k&Z
M electronic = 610 mm / 5.3 mm = 115 x v42Z&PO

The overall magnification then is: +cC$4t0$^A

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x .@3bz

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm 6}GcMhU< r

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？ `8G {-_
