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： `hzd|GmX
Example: an erythrocyte (O 8 μm) is photographed using Mk<m6E$L
the Achroplan objective 100x. The TV adapter has the KUb J e)}g
factor 0.5x: Sz RL}} I

M optical = 100 x 0.5 = 50 x QI.t&sCh5

The active sensor diagonal of the 1/3”-chip CCD-camera GM:, CJ?
is 5.3 mm. The monitor in the lecture room has a useful 9 _eS`,'
image diagonal of 61 cm (= 610 mm). Lg8 ]dBXu

M electronic = 610 mm / 5.3 mm = 115 x o.v2z~V

The overall magnification then is: -P2 @mx%

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm u]R $]& <

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？ wtq,`'B
