Compatible Size List for Eyepieces and Ocular Micrometers
| The required ocular micrometer size varies by microscope manufacturer and
eyepiece model (part number). Please check the table below before placing your order. |
| Nikon Eyepiece Models |
| In addition to magnification, eyepieces may be labeled with "CFW 10x/22,"
etc. The "/22" indicates the field of view, not the micrometer's diameter. |

are 1.0mm. However, since the printed surface faces the objective lens, the optical distance remains the same, ensuring no issues in use. |
