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： !=C4=xv
Example: an erythrocyte (O 8 μm) is photographed using =jdO2MgSg*
the Achroplan objective 100x. The TV adapter has the v{Cts3?Br
factor 0.5x: }OO(u C2
0S@O] k)
M optical = 100 x 0.5 = 50 x h: :'s&|
DX.u"&Mm
The active sensor diagonal of the 1/3”-chip CCD-camera F\ !;}z
is 5.3 mm. The monitor in the lecture room has a useful Q:Q) -|,
image diagonal of 61 cm (= 610 mm). +7?p& -r)x
xkR--/f
M electronic = 610 mm / 5.3 mm = 115 x LXj2gsURu%
.5 8>KBj(
The overall magnification then is: >T{9-_#P
*leQd^47
Moverall = Moptical x Melectronic = 50 x 115 = 5750 x 5;{d*L
,I q+ v
The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm u2K{3+r`'
or 46 mm = 4.6 cm ~rE U83

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？ q@;WXH O0
