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： lgefTT GX)
Example: an erythrocyte (O 8 μm) is photographed using p-6T,' )
the Achroplan objective 100x. The TV adapter has the 5 QG?*Z~?7
factor 0.5x: ^= qL[S6/M

M optical = 100 x 0.5 = 50 x R E9 `T

The active sensor diagonal of the 1/3”-chip CCD-camera \

is 5.3 mm. The monitor in the lecture room has a useful WFfn:WSWU

M electronic = 610 mm / 5.3 mm = 115 x pvdCiYo1r

The overall magnification then is: K#x|/b'5d

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm Z1U@xQj

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？ d M;v39
