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： !>&G+R +k
Example: an erythrocyte (O 8 μm) is photographed using A{\DzUV9,
the Achroplan objective 100x. The TV adapter has the G/ w@2lYx
factor 0.5x: KvI /!hl\
S(rnVsW%Ki
M optical = 100 x 0.5 = 50 x ~4c,'k @
C;9P6^Oz
The active sensor diagonal of the 1/3”-chip CCD-camera 9<"F3F0|
is 5.3 mm. The monitor in the lecture room has a useful U@(8)[?nxn
image diagonal of 61 cm (= 610 mm). %{me <\(

-w|~y';
M electronic = 610 mm / 5.3 mm = 115 x jP<6Q|5F

The overall magnification then is: W&m3"~BJ
E^~ {thf

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm ?wjk=hM2

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？ n "R$b:
