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： ? 0u"No52m
Example: an erythrocyte (O 8 μm) is photographed using qm#?DSLap
the Achroplan objective 100x. The TV adapter has the ~BTm6*'h
factor 0.5x: tag)IWAiE
?!F<xi:
M optical = 100 x 0.5 = 50 x ?mV2| ;

The active sensor diagonal of the 1/3”-chip CCD-camera ~eTp( XG
is 5.3 mm. The monitor in the lecture room has a useful aiX4;'$x!
image diagonal of 61 cm (= 610 mm). {|%^'lS
}x{1{Bw>Y
M electronic = 610 mm / 5.3 mm = 115 x 2N-p97"g

The overall magnification then is: rx]Q,;"

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x ?l[#d7IB

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm _ZWU~38PM

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？ Y$^vA[]c>
