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： +)fl9>Mb
Example: an erythrocyte (O 8 μm) is photographed using pc w^W
the Achroplan objective 100x. The TV adapter has the

factor 0.5x: ##!) }i

M optical = 100 x 0.5 = 50 x h+x"?^

The active sensor diagonal of the 1/3”-chip CCD-camera T }X#I'Z
is 5.3 mm. The monitor in the lecture room has a useful B;?"R
image diagonal of 61 cm (= 610 mm). g(Jzu'

M electronic = 610 mm / 5.3 mm = 115 x HhaUC?JtSK

The overall magnification then is: u5 EHzoq

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x |.Bb Pfe8f

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm _1`*&k

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？ pI
