Tag nrho magnification = lub hom phiaj magnification * digital magnification
Lub hom phiaj lens magnification = Loj lub hom phiaj lens magnification * Lens magnification
Digital magnification = saib loj * 25.4 / CCD phiaj kab pheeb ces kaum loj
CCD lub hom phiaj diagonal loj: 1/3 "yog 6mm, 1/2" yog 8mm, 2/3" yog 11mm
Piv txwv li: 0.7X - 4.5X lens nrog 1/3 "CCD thiab 14" saib
Digital magnification: 14 * 25.4 / 6 = 59.3X
Tag nrho cov magnification: (0.7X - 4.5X) * 59.3 = 41.5X - 266.9X
Tom qab ntawd raws li cov kev teeb tsa saum toj no, tag nrho qhov kev nthuav dav ntawm cov cuab yeej no tau hloov kho tsis tu ncua ntawm 41.5X thiab 266.9X.
