In addition to the magnification, the eyepiece may be labeled "CFW
10x/22" etc. The "/22" part is the number of field of view and not the diameter of the micrometer. |

(*) The thickness of Olympus micrometer with φ24mm is 1.5mm, but the thickness
of our micrometer is 1.0 mm. Since the printing surface is on the objective lens's side, the optical distance from the objective lens is the same, and there is no problem in use. |
