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： xnA rYm
Example: an erythrocyte (O 8 μm) is photographed using UC QL~
the Achroplan objective 100x. The TV adapter has the `J C!u c
factor 0.5x: uBM1;9h
-`( :L[
M optical = 100 x 0.5 = 50 x q+ .=f.+Z
XH/|jE.9^|
The active sensor diagonal of the 1/3”-chip CCD-camera Y\rKw!u_!
is 5.3 mm. The monitor in the lecture room has a useful >[#4Pb7_ Y
image diagonal of 61 cm (= 610 mm). :c\NBKHv*
t 6tqv
M electronic = 610 mm / 5.3 mm = 115 x m+L:\mvA
) }EwEM
The overall magnification then is: ,Vogo5~X
"/q6E
Moverall = Moptical x Melectronic = 50 x 115 = 5750 x %Z .!Bm:

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm vO\CPb

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？ vt1!|2{
