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： @ * *]o
Example: an erythrocyte (O 8 μm) is photographed using ],ISWb
the Achroplan objective 100x. The TV adapter has the h}jE=T5Hc
factor 0.5x: 8d"Ff

M optical = 100 x 0.5 = 50 x 3 At%TA:

The active sensor diagonal of the 1/3”-chip CCD-camera sM'%apM#
is 5.3 mm. The monitor in the lecture room has a useful ' e06QMp@
image diagonal of 61 cm (= 610 mm). a{7'qmN1

M electronic = 610 mm / 5.3 mm = 115 x V q<\ix Ri

The overall magnification then is: > hmB V7nR

Moverall = Moptical x Melectronic = 50 x 115 = 5750 x $Q< >M B7

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm "_

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？ 6#/v:;bF
