0.8A shows the central axis of 0.75mm; 0.8mm of the optical axis, with a tight, rotates along with the optical axis.
1.5A displays the central axis of 1.45mm; 1.5mm of the optical axis, with a tight, rotates along with the optical axis.
2A shows the central axis of 1.95mm; 2mm of the optical axis, with a tight, rotates along with the optical axis.
2.5A shows the central axis of 2.45mm; 2.5mm of the optical axis, with a tight, rotates together with the optical axis.
3A shows the central axis of 2.95mm; 3mm of the optical axis, with a tight, rotates along with the optical axis.
2B represents the central axis of 2.05mm; and the optical axis of 2mm, loosely fitted, unfastened to rotate at the optical axis.
