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： \P[Y`LYL
Example: an erythrocyte (O 8 μm) is photographed using t^&Cx h
the Achroplan objective 100x. The TV adapter has the Lw1Yvtn
factor 0.5x: G0Iw-vf
U svl}{L[
M optical = 100 x 0.5 = 50 x :'Vf

The active sensor diagonal of the 1/3”-chip CCD-camera <|HV. O/!
is 5.3 mm. The monitor in the lecture room has a useful ' B |JAi?
image diagonal of 61 cm (= 610 mm). yNPVOp*
$z 6_@`[
M electronic = 610 mm / 5.3 mm = 115 x cTi fC1Pf

The overall magnification then is: 9+|$$)

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm =nHUs1rKn

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？ -OV&Md:~
