Total magnification = objective magnification * digital magnification
Objective lens magnification = Large objective lens magnification * Lens magnification
Digital magnification = monitor size * 25.4/CCD target diagonal size
CCD target diagonal size: 1/3″ is 6mm, 1/2″ is 8mm, 2/3″ is 11mm
Example: 0.7X – 4.5X lens with 1/3″ CCD and 14″ monitor
Digital magnification: 14 * 25.4 / 6 = 59.3X
Total magnification: (0.7X – 4.5X) * 59.3=41.5X – 266.9X
Then according to the above configuration, the total magnification of this equipment is continuously adjustable between 41.5X and 266.9X
