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： s7 .p$r
Example: an erythrocyte (O 8 μm) is photographed using EOBs}M;
the Achroplan objective 100x. The TV adapter has the "'F;lzq
factor 0.5x: F[7Kw"~J

The active sensor diagonal of the 1/3”-chip CCD-camera @Ge>i5q
is 5.3 mm. The monitor in the lecture room has a useful \=w'HZH#+
image diagonal of 61 cm (= 610 mm). ,XeyE ;| |

M electronic = 610 mm / 5.3 mm = 115 x s,$Z ("B

The overall magnification then is: mZbWRqP[|_

The erythrocyte appears on the screen with 8 μm x 5750 = 46000 μm GJIWG&C03

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？
