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： tV*g1)'zX
Example: an erythrocyte (O 8 μm) is photographed using yXppu [=
the Achroplan objective 100x. The TV adapter has the U&wVe$
factor 0.5x: /_x?PiL
isDBNXV:
M optical = 100 x 0.5 = 50 x \ zhT1#O

The active sensor diagonal of the 1/3”-chip CCD-camera (IIOKx _
is 5.3 mm. The monitor in the lecture room has a useful }v0oFY$u`H
image diagonal of 61 cm (= 610 mm). GZXUB0W\@)
A37Z;/H~k
M electronic = 610 mm / 5.3 mm = 115 x X dLB1H
I#Iu:,OT
The overall magnification then is: S<88>|&n]

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x +S^Uw'L$=T

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm )3'/g`c
or 46 mm = 4.6 cm o8

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？ B\KvKT|\
